《Formation of Cyclopropanes via Activation of (γ-Methoxy)alkyl Gold(I) Complexes with Lewis Acidsã€?was written by Kim, Nana; Widenhoefer, Ross A.. Recommanded Product: Bis[(pinacolato)boryl]methane And the article was included in Organometallics in 2020. The article conveys some information:

Treatment of the gold 3-methoxy-3-phenylpropyl complex (P)AuCH2CH2CH(OMe)Ph [P = P(t-Bu)2o-biphenyl] with AlCl3 at -78° led to the immediate (â‰? min) formation of a 4:1 mixture of phenylcyclopropane and (1-methoxypropyl)benzene in 86 ± 5% combined yield. Lewis acid activation of the stereochem. pure isotopomer erythro-(P)AuCH2CHDCH(OMe)Ph led to the formation of cis-2-deuterio-1-phenylcyclopropane in 84 ± 5% yield as a single stereoisomer, which established that cyclopropanation occurred with inversion of the γ-stereocenter. Similarly, ionization of the stereochem. pure cyclohexyl gold complex cis-(P)AuCHCH2CH(OMe)CH2CH2CH2 at -78° formed bicyclo[3.1.0]hexane in 82% ± 5% yield, which validated a low energy pathway for cyclopropanation involving inversion of the α-stereocenter. Taken together, these observations are consistent with a mechanism for cyclopropane formation involving backside displacement of both the γ-C leaving group and the α-C (L)Au+ fragment via a W-shaped transition state.Bis[(pinacolato)boryl]methane(cas: 78782-17-9Recommanded Product: Bis[(pinacolato)boryl]methane) was used in this study.

In 2018,ACS Catalysis included an article by Ahn, Seihwan; Sorsche, Dieter; Berritt, Simon; Gau, Michael R.; Mindiola, Daniel J.; Baik, Mu-Hyun. HPLC of Formula: 78782-17-9. The article was titled 《Rational Design of a Catalyst for the Selective Monoborylation of Methaneã€? The information in the text is summarized as follows:

Combined computational and exptl. studies elucidate the mechanism and suggest rational design and optimization strategies of a bis(phosphine) supported Ir catalyst for methane monoborylation. The activation of the C-H bond in methane via oxidative addition using an Ir(III)-polypyridyl complex carrying three pinacolboryl ligands is modeled computationally. This model shows that the use of the soft Lewis base ligand such as bis(dimethylphosphino)ethane (dmpe) lowers the activation barrier of the rate determining step as it facilitates polarization of the metal center, lowering the barrier of the oxidative addition to afford a seven-coordinate Ir(V) intermediate. The exptl. optimization of this reaction using high throughput methods show that up to 170 turnovers can be achieved at 150° (500 psi) within 16 h using bis(pinacolato)diboron, a well-defined homogeneous and monomeric catalyst (dmpe)Ir(COD)(Cl) that is readily available from com. precursors, with selectivity for the monoborylation product. High-boiling cyclic aliphatic solvents decalin and cyclooctane also prove suitable for this reaction, while being inert towards borylation. In accordance with the lower calculated activation barrier, catalytic turnover is also observed at 120° with up to 50 turnovers over 4 days in cyclohexane solvent. The borylation of methane is only formed via one catalytic cycle, and buildup of pinacolborane, a side product from methane borylation with bis(pinacolato)diboron, inhibits catalytic activity.Bis[(pinacolato)boryl]methane(cas: 78782-17-9HPLC of Formula: 78782-17-9) was used in this study.

The article was titled 《Chemo- and Stereoselective Dearomative Coupling of Indoles and Bielectrophilic β-Imino Boronic Esters via Imine-Induced 1,2-Boronate Migrationã€? and you may find the article in Organic Letters.Name: Bis[(pinacolato)boryl]methane The information in the text is summarized as follows:

A new imine-induced 1,2-boronate migration was developed for achieving chemo- and stereoselective dearomative coupling of C3-substituted indoles and bielectrophilic β-imino boronic esters, providing rapid access to complex chiral indoline boronic esters with four stereocenters including an all-C quaternary stereocenter and a tertiary α-aminoboronic ester. By contrast, coupling of indoles without C3 substitution and β-imino boronic esters provided tetrahydro-1H-pyrido[4,3-b]indoles via imine-induced 1,2-boronate migration followed by deborylative rearomatization.

In 2017,Li, Lei; Gong, Tianjun; Lu, Xi; Xiao, Bin; Fu, Yao published 《Nickel-catalyzed synthesis of 1,1-diborylalkanes from terminal alkenes》.Nature Communications published the findings.HPLC of Formula: 78782-17-9 The information in the text is summarized as follows:

Organoboron compounds play an irreplaceable role in synthetic chem. and the related transformations based on the unique reactivity of C-B bond are potentially the most efficient methods for the synthesis of organic mols. The synthetic importance of multiboron compounds in C-C bond formation and function transformation reactions is growing and the related borations of activated or nonactivated alkenes have been developed recently. However, introducing directly two boron moieties into the terminal sites of alkenes giving 1,1-diborylalkanes in a catalytic fashion has not been explored yet. Here authors describe a synthetic strategy of 1,1-diborylalkanes via a Ni-catalyzed 1,1-diboration of readily available terminal alkenes. This methodol. shows high level of chemoselectivity and regioselectivity and can be used to convert a large variety of terminal alkenes, such as vinylarenes, aliphatic alkenes and lower alkenes, to 1,1-diborylalkanes.Bis[(pinacolato)boryl]methane(cas: 78782-17-9HPLC of Formula: 78782-17-9) was used in this study.
