In 2022,Zhang, Wanzheng; Guillen-Soler, Melanie; Moreno-Da Silva, Sara; Lopez-Moreno, Alejandro; Gonzalez, Luisa R.; Gimenez-Lopez, Maria del Carmen; Perez, Emilio M. published an article in Chemical Science. The title of the article was 《Mechanical interlocking of SWNTs with N-rich macrocycles for efficient ORR electrocatalysis》.Electric Literature of C12H17BO2 The author mentioned the following in the article:

Substitutional N-doping of single-walled carbon nanotubes is a common strategy to enhance their electrocatalytic properties in the oxygen-reduction reaction (ORR). Here, we explore the encapsulation of SWNTs within N-rich macrocycles as an alternative strategy to display electroactive sites on the surface of SWNTs. We design and synthesize four types of mech. interlocked derivatives of SWNTs (MINTs) by combining two types of macrocycles and two types of SWNT samples. Comprehensive electrochem. characterization of these MINTs and their reference SWNTs allows us to establish structure-activity relationships. First, we show that all MINT samples are superior electrocatalysts compared to pristine SWNTs, which serves as general validation of our strategy. Secondly, we show that macrocycles displaying both N atoms and carbonyl groups perform better than those with N atoms only. Finally, we demonstrate that a tighter fit between macrocycles and SWNTs results in enhanced catalytic activity and stability, most likely due to a more effective charge-transfer between the SWNTs and the macrocycles. These results, focusing on the ORR as a testbed, show the possibility of understanding electrocatalytic performance of SWNTs at the mol. level and thus enable the design of more active and more stable catalysts in the future. In the experiment, the researchers used many compounds, for example, 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane(cas: 24388-23-6Electric Literature of C12H17BO2)

Synthetic Route of C12H17BO2In 2021 ,《Mechanistic insights into the dearomative diborylation of pyrazines: a radical or non-radical process?》 appeared in Dalton Transactions. The author of the article were Gao, Liuzhou; Zhang, Hanyin; Liu, Xueting; Wang, Guoqiang; Li, Shuhua. The article conveys some information:

The mechanisms of the dearomative diborylation of pyrazines were studied via a combination of d. functional theory (DFT) calculations and exptl. studies. DFT calculations revealed that a non-radical mechanism involving two successive [3,3]-σ-rearrangement-type processes is responsible for the diborylation of pyrazine with bis(pinacolato)diboron (B2pin2). However, this non-radical process is highly unfavorable for the diborylation reaction of sterically hindered pyrazine (2,3-dimethylpyrazine). For the diboration reaction of 2,3-dimethylpyrazine with B2pin2 in the presence of 2,6-dichloro-4,4′-bipyridine as the catalyst, 4,4′-bipyridine-mediated radical pathway proceeding through a B-B homolytic cleavage/boryl radical addition is preferred. Control experiments combined with kinetic studies provided supportive evidence for the proposed mechanism. In the experimental materials used by the author, we found 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane(cas: 24388-23-6Synthetic Route of C12H17BO2)

The author of 《Low-Coordinate NHC-Zinc Hydride Complexes Catalyze Alkyne C-H Borylation and Hydroboration Using Pinacolborane》 were Procter, Richard J.; Uzelac, Marina; Cid, Jessica; Rushworth, Philip J.; Ingleson, Michael J.. And the article was published in ACS Catalysis in 2019. Recommanded Product: 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane The author mentioned the following in the article:

Organozinc compounds containing sp, sp2, and sp3 C-Zn moieties undergo transmetalation with pinacolborane (HBPin) to produce Zn-H species and organoboronate esters (RBPin). This Zn-C/H-B metathesis step is key to enabling Zn-catalyzed borylation reactions, and it was used in this work to develop both terminal alkyne C-H borylation and internal alkyne hydroboration. These two conversions can be combined in one pot to achieve the Zn-catalyzed conversion of terminal alkynes to 1,1-diborylated alkenes without isolation of the sensitive (to protodeboronation) alkynyl boronate ester intermediates. Mechanistic studies involving the isolation of intermediates, stoichiometric experiments, and DFT calculations all support mechanisms involving organozinc species that undergo metathesis with HBPin. Also, Zn-catalyzed hydroboration can proceed via a hydrozincation step, which does not require any exogenous catalyst in contrast to all previously reported alkyne hydrozincations. Bulky N-heterocyclic carbenes (NHCs) are key for effective catalysis as the NHC steric bulk enhances the stability of the NHC-Zn species present during catalysis and provides access to low-coordinate (NHC)Zn-H cations that are electrophilic yet Bronsted basic. This work provides an alternative approach to access synthetically desirable pinacol-organoboronate esters using earth-abundant metal-based borylation catalysts.4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane(cas: 24388-23-6Recommanded Product: 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane) was used in this study.

Shang, Yong; Wu, Chenggui; Gao, Qianwen; Liu, Chang; Li, Lisha; Zhang, Xinping; Cheng, Hong-Gang; Liu, Shanshan; Zhou, Qianghui published their research in Nature Communications in 2021. The article was titled 《Diversity-oriented functionalization of 2-pyridones and uracils》.Synthetic Route of C12H17BO2 The article contains the following contents:

A palladium/norbornene cooperative catalysis enabled dual-functionalization of iodinated 2-pyridones I (R = H, Me, Bn, mesityl, MOM, PMB; R1 = CH3, F, Cl, CH2OCH3, CH2C(O)2CH3, 4-ethoxy-4-oxobutyl) and uracils like 6-iodo-1,3-bis(phenylmethyl)-2,4(1H,3H)-pyrimidinedione and 5-iodo-1,3-bis(phenylmethyl)-2,4(1H,3H)-pyrimidinedione. The success of this research depends on the use of two unique norbornene derivatives as the mediator. Readily available alkyl halides R2X (R2 = Me, 4-ethoxy-4-oxobutyl, Bn, etc.; X = Br, I)/tosylate like Me tosylate and aryl bromides R2Br are utilized as ortho-alkylating and -arylating reagents, resp. Widely accessible ipso-terminating reagents, including H/DCO2Na, boronic acid like methylboronic acid/ester like pinacol phenylboronate, terminal alkene R3CH=CH2 (R3 = CH3, CH=CHC6H5, CH=CH2, etc.) and alkyne like triisopropylsilylethyne are compatible with this protocol. Thus, a large number of valuable 2-pyridone derivatives, II including deuterium/CD3-labeled 2-pyridones, bicyclic 2-pyridones, 2-pyridone-fenofibrate conjugate, axially chiral 2-pyridone (97% ee), as well as uracil and thymines III and 1,3-dibenzyl-6-methyl-5-((triisopropylsilyl)ethynyl)pyrimidine-2,4(1H,3H)-dione can be quickly prepared in a predictable manner (79 examples reported), which will be very useful in new drug discovery.

In 2019,Nature Chemistry included an article by Fawcett, Alexander; Biberger, Tobias; Aggarwal, Varinder K.. Recommanded Product: 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane. The article was titled 《Carbopalladation of C-C σ-bonds enabled by strained boronate complexes》. The information in the text is summarized as follows:

Transition-metal-catalyzed cross-coupling reactions, particularly those mediated by Pd, are some of the most broadly used chem. transformations. The fundamental reaction steps of such cross-couplings typically include oxidative addition, transmetalation, carbopalladation of a π-bond and/or reductive elimination. Herein, the authors describe an unprecedented fundamental reaction step: a C-C σ-bond carbopalladation. Specifically, an aryl Pd(II) complex interacts with a σ-bond of a strained bicyclo[1.1.0]butyl boronate complex to enable addition of the aryl Pd(II) species and an organoboronic ester substituent across a C-C σ-bond. The overall process couples readily available aryl triflates and organoboronic esters across a cyclobutane unit with total diastereocontrol. The pharmaceutically relevant 1,1,3-trisubstituted cyclobutane products are decorated with an array of modular building blocks, including a boronic ester that can be readily derivatized.

Computed Properties of C12H17BO2In 2021 ,《Stereoselectivity in spontaneous assembly of rolled incommensurate carbon bilayers》 was published in Nature Communications. The article was written by Matsuno, Taisuke; Ohtomo, Yutaro; Someya, Maki; Isobe, Hiroyuki. The article contains the following contents:

The periodicity of two-dimensional entities can be manipulated by their stacking assembly, and incommensurate stacks of bilayers are attracting considerable interest in materials science. Stereoisomerism in incommensurate bilayers was first noted with incommensurate double-wall carbon nanotubes composed of helical carbon networks, but the lack of structural information hampered the chem. understanding such as the stereoselectivity during bilayer formation. In this study, we construct a finite mol. version of incommensurate carbon bilayers by assembling two helical cylindrical mols. in solution An outer cylindrical mol. is designed to encapsulate a small-bore helical cylindrical mol., and the spontaneous assembly of coaxial complexes proceeds in a stereoselective manner in solution with a preference for heterohelical combinations over diastereomeric, homohelical combinations. The rational design of incommensurate bilayers for material applications may be facilitated by the design and development of mol. versions with discrete structures with at. precision. The results came from multiple reactions, including the reaction of 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane(cas: 24388-23-6Computed Properties of C12H17BO2)

The author of 《Molecular design to increase the photosensitivity of photochromic phenoxyl-imidazolyl radical complexes》 were Li, Ruiji; Arai, Hiroki; Kobayashi, Yoichi; Mutoh, Katsuya; Abe, Jiro. And the article was published in Materials Chemistry Frontiers in 2019. COA of Formula: C12H17BO2 The author mentioned the following in the article:

Photochromic mols. have received a lot of interest in potential applications. The development of the phenoxyl-imidazolyl radical complex (PIC), which generates two nonequivalent radicals upon light irradiation along with the fast photochem. reaction, is crucial for photoresponsive materials. However, as a novel photochromic compound, the low photosensitivity of PIC derivatives has limited their practical applications. Herein, increased photosensitivity and absorption coefficients of PIC derivatives were achieved while keeping the thermal back reaction rate by introducing the substitution of aryl groups. This strategy gives significant insight into the development of desirable fast photochromic compounds based on the PIC framework.
