Li, Zhiwen published the artcileHighly selective oxidation of organosilanes with a reusable nanoporous silver catalyst, COA of Formula: C6H16OSi, the publication is Catalysis Communications (2014), 53-56, database is CAplus.

Room temperature highly selective oxidation of organosilanes to organosilanols and organosilyl ethers is achieved in liquid-phase with dealloyed nanoporous silver catalysts. In both cases, aromatic and aliphatic silanes can be effectively converted into the corresponding silanols and silyl ethers by using water and alcs. as oxidant, resp. Moreover, hydrogen gas is the only byproduct and the catalyst can be recycled for several times without evident loss of activity and selectivity.

Anderson, Ryan T. published the artcileDirect Conversion of Hydride- to Siloxane-Terminated Silicon Quantum Dots, Related Products of alcohols-buliding-blocks, the publication is Journal of Physical Chemistry C (2016), 120(45), 25822-25831, database is CAplus.

Peripheral surface functionalization of hydride-terminated silicon quantum dots (SiQD) is necessary in order to minimize their oxidation/aggregation and allow for solution processability. Historically thermal hydrosilylation addition of alkenes and alkynes across the Si-H surface to form Si-C bonds has been the primary method to achieve this. The authors demonstrate a mild alternative approach to functionalize hydride-terminated SiQDs using bulky silanols in the presence of free-radical initiators to form stable siloxane (∼Si-O-SiR₃) surfaces with hydrogen gas as a byproduct. This offers an alternative to existing methods of forming siloxane surfaces that require corrosive Si-Cl based chem. with HCl byproducts. A 52 nm blue shift in the photoluminescent spectra of siloxane vs. alkyl-functionalized SiQDs is observed that we explain using computational theory. Model compound synthesis of silane and silsesquioxane analogs is used to optimize surface chem. and elucidate reaction mechanisms. Thorough characterization on the extent of siloxane surface coverage is provided using FTIR and XPS. TEM is used to demonstrate SiQD size and integrity after surface chem. and product isolation.

Li, Jun published the artcileSynthesis, properties and drug potential of the photosensitive alkyl- and alkylsiloxy-ligated silicon phthalocyanine Pc 227, SDS of cas: 597-52-4, the publication is Photochemical & Photobiological Sciences (2014), 13(12), 1690-1698, database is CAplus and MEDLINE.

The photosensitive, alkyl- and alkylsiloxy-ligated Si phthalocyanine, SiPc[(CH₂)₃SH][OSiMe₂(CH₂)₃NMe₂], Pc 227, was prepared and characterized. This phthalocyanine yields the exptl. photodynamic therapy (PDT) drug Pc 4, SiPc[OH][OSiMe₂(CH₂)₃NMe₂], when irradiated with red light. To provide an understanding of the process by which Pc 227 and other alkyl-alkylsiloxysilicon phthalocyanines such as Pc 227 are photolyzed, bond dissociation energy, natural bond orbital (NBO) charge distribution, spin d. distribution, nucleus-independent chem. shift (NICS), and electron localization function (ELF) calculations were carried out on two models related to it. These show that the lowest energy pathway for the photolysis of Pc 227 is a homolysis involving a phthalocyanine π radical having a low Si_Pc-C bond dissociation energy. The promise of the results of this study for synthetic chem. and drug development is discussed.

Cao, Jilei published the artcileMetal-free hydrogen evolution cross-coupling enabled by synergistic photoredox and polarity reversal catalysis, Computed Properties of 597-52-4, the publication is Green Chemistry (2021), 23(22), 8988-8994, database is CAplus.

A synergistic combination of photoredox and polarity reversal catalysis enabled a hydrogen evolution cross-coupling of silanes with H₂O, alcs., phenols, and silanols, which afforded the corresponding silanols, monosilyl ethers, and disilyl ethers, resp., in moderate to excellent yields. The dehydrogenative cross-coupling of Si-H and O-H proceeded smoothly with broad substrate scope and good functional group compatibility in the presence of only an organophotocatalyst 4-CzIPN and a thiol HAT catalyst, without the requirement of any metals, external oxidants and proton reductants, which is distinct from the previously reported photocatalytic hydrogen evolution cross-coupling reactions where a proton reduction cocatalyst such as a cobalt complex is generally required. Mechanistically, a silyl cation intermediate is generated to facilitate the cross-coupling reaction, which therefore represents an unprecedented approach for the generation of silyl cation via visible-light photoredox catalysis.

Zhang, Kaifu published the artcileSynthesis of a Gold-Metal Oxide Core-Satellite Nanostructure for In Situ SERS Study of CuO-Catalyzed Photooxidation, Application of Triethylsilanol, the publication is Angewandte Chemie, International Edition (2020), 59(41), 18003-18009, database is CAplus and MEDLINE.

This work reports on an assembling-calcining method for preparing gold-metal oxide core-satellite nanostructures, which enable surface-enhanced Raman spectroscopic detection of chem. reactions on metal oxide nanoparticles. By using the nanostructure, we study the photooxidation of Si-H catalyzed by CuO nanoparticles. As evidenced by the in situ spectroscopic results, oxygen vacancies of CuO are found to be very active sites for oxygen activation, and hydroxyl radicals (·OH) adsorbed at the catalytic sites are likely to be the reactive intermediates that trigger the conversion from silanes into the corresponding silanols. According to our finding, oxygen vacancy-rich CuO catalysts are confirmed to be of both high activity and selectivity in photooxidation of various silanes.

Chlorosilanes are versatile reagents in organic synthesis and material science. A mild pathway is now reported for the quant. conversion of hydrosilanes to silyl chlorides under visible-light irradiation using neutral eosin Y as a hydrogen-atom-transfer photocatalyst and dichloromethane as a chlorinating agent. Stepwise chlorination of di- and trihydrosilanes was achieved in a highly selective fashion assisted by continuous-flow micro-tubing reactors. The ability to access silyl radicals using photocatalytic Si-H activation promoted by eosin Y offers new perspectives for the synthesis of valuable silicon reagents in a convenient and green manner.

Pedrick, E. A. published the artcileReductive silylation of a uranyl dibenzoylmethanate complex: an example of controlled uranyl oxo ligand cleavage, Application of Triethylsilanol, the publication is Chemical Science (2014), 5(8), 3204-3213, database is CAplus.

Reaction of UO₂(dbm)₂(THF) (dbm = OC(Ph)CHC(Ph)O) with 1 equiv of R₃SiH (R = Ph, Et), in the presence of B(C₆F₅)₃, gave U(OB{C₆F₅}₃)(OSiR₃)(dbm)₂(THF) (R = Ph, 1; Et, 2), which were isolated as red-orange crystalline solids in good yields. The addition of 1 equiv of H(dbm) to 2 results in protonation of the -OSiEt₃ ligand and formation of U(OB{C₆F₅}₃)(dbm)₃ (4) in 33% yield, along with formation of HOSiEt₃. Furthermore, addition of HOSiEt₃ and 1 equiv of THF to 4, results in the formation 2, revealing that this process is reversible. The two-step conversion of UO₂(dbm)₂(THF) to 4 represents a rare example of controlled uranyl oxo ligand cleavage at ambient temperature and pressure. Comparison of diffraction and d. functional theory data for 4 suggests the inverse trans influence (ITI), with a very shallow potential energy well for distortion along the trans U-O bond.

Yap, Chew Pheng published the artcileMetal-free catalytic hydrogen production from a polymethylhydrosilane-water mixture, Safety of Triethylsilanol, the publication is RSC Advances (2016), 6(7), 5903-5906, database is CAplus.

Hydrogen gas is the most promising carbon-free energy carrier although its on-demand generation remains a formidable challenge. One of the potential pathways for generating hydrogen is through hydrolytic oxidation of organosilanes. Here, we demonstrate that the hydroxide ion OH^– serves as a potent room-temperature metal-free catalyst in the hydrolytic oxidation of polymethylhydrosilane, PMHS to hydrogen gas and the corresponding silanol with a turnover number and turnover frequency in excess of 200 and 8 min^-1 resp. Kinetic studies suggest the hydrogen generation rate is first order with respect to PMHS and OH^– but zero order with respect to water. The first step of the reaction, where the Si center of PMHS is attacked by the OH^– ion, is believed to be the rate-determining step.
