Treatment of Cr[N(SiMe3)2]2(THF)2 with HOSiR3 (R = Et, iPr) in THF afforded the bridged CrII siloxide complexes Cr3(OSiEt3)2(μ-OSiEt3)4(THF)2 and Cr2(OSiiPr3)2(μ-OSiiPr3)2(THF)2 in high yield. Exposure of these compounds to vacuum in aliphatic solvents led to the loss of coordinated THF and to the formation of the homoleptic chromous siloxides Cr4(μ-OSiEt3)8 and Cr3(OSiiPr3)2(μ-OSiiPr3)4, resp., in moderate to high yield. Use of TMEDA as a potentially bidentate donor mol. gave the monomeric cis-coordinated siloxide Cr(OSiiPr3)2(tmeda) (tmeda = N,N,N’,N’-tetramethylethane-1,2-diamine). Oxidation of Cr2(OSiiPr3)2(μ-OSiiPr3)2(THF)2 with CHI3 and C2Cl6 produced the trigonal bipyramidal chromic compound CrIII(OSiiPr)3(THF)2 and asym. coordinated Cr2Cl3(OSiiPr3)3(THF)3, resp. Magnetic measurements (Evans and SQUID) hinted at (a) antiferromagnetic interactions between the CrII centers, (b) revealed higher effective magnetic moments (μeff) for cis-coordinated monomeric heteroleptic complexes compared to trans-coordinated ones, and (c) pointed out the highest (μeff) for the tetranuclear complex Cr4(μ-OSiEt3)8 (6.26μB, SQUID, 300 K; Cr···Cradjacent average 2.535 Å).

Herein, the first metal-free visible-light-mediated aerobic oxidation of silanes to silanols using 2 mol% Rose Bengal as the catalyst, air (O2) as the oxidant and water as the additive is reported. While this method produces various silanols in a simple, cost-effective, efficient (92%-99% yields) and scalable fashion, its reaction mechanism is very different than the reported ones associated with metal catalysis.

Owing to their versatile application possibilities, silsesquioxanes (SQs) are of considerable interest for creating hybrid inorganic-organic materials. In this report, two novel and independent strategies for the direct attachment of boron functionalities to silsesquioxanes are presented. Encouraged by our previous work concerning the synthesis of borasiloxanes through the catalyst-free dehydrogenative coupling of silanols and boranes, we decided to apply our method to a synthesis of various boron-functionalized silsesquioxanes. During our tests, we also investigated the activity of scandium(III) triflate, which we have previously used as an excellent catalyst for the obtaining of Si-O-Si and Si-O-Ge moieties. As a result, we also discovered a novel approach for the O-borylation of Si-OH groups in silsesquioxanes with allylborane. Both routes are highly chemoselective and efficiently lead to the obtaining of Si-O-B moiety under air atm. and at room temperature

Shimizu, Ken-ichi published the artcileSurface Oxygen-Assisted Pd Nanoparticle Catalysis for Selective Oxidation of Silanes to Silanols, Computed Properties of 17877-23-5, the publication is Chemistry – A European Journal (2012), 18(8), 2226-2229, S2226/1-S2226/12, database is CAplus and MEDLINE.

Oxygen-adsorbed Pd surfaces show higher reactivity for water dissociation than clean Pd surfaces. Thus, carbon-supported Pd nanoparticles with surface oxygen atoms show higher activity for hydrolytic oxidation of silanes than previously reported catalysts. The synthetic utility of this catalyst is quite high because the catalyst, readily prepared from com. Pd/C, is easily recovered and reused, and shows high activity in oxidation of various silanes. This is a surface-science driven strategy of catalyst design for green organic synthesis. E.g., hydration of Et3SiH in presence of carbon-supported Pd nanoparticles covered with O gave >99% Et3SiOH, with TON = 20,000.

3,4-Dimethoxybenz-1-yne and 2-siloxylated furans without or with a bromine atom at C-3 undergo Diels-Alder reactions with orientational selectivity. Hydrolysis furnished a bromine-free or a bromine-containing naphthalene, resp. Bromination of the former provided a regioisomer of the latter. Either of the two compounds was processed to give a variety of unnatural naphthoquinonopyrano-γ-lactones. This occurred by a succession of (1) Heck coupling, (2) asym. dihydroxylation, (3) oxa-Pictet-Spengler cyclization, and (4) oxidation The fifteen monomeric naphthoquinonopyrano-γ-lactone structures that we prepared resemble the natural product (-)-arizonin C1 (I) or its C-5 epimer. Accordingly, they represent hexasubstituted naphthalenes likewise. The sixteenth naphthoquinonopyrano-γ-lactone that we synthesized is a kind of dimer. Its moieties are bridged differently than those in naturally occurring naphthoquinonopyrano-γ-lactone dimers.

The oxidation of organosilanes to silanols constitutes an attractive transformation for both industry and academia. Bypassing the need for stoichiometric oxidants or precious metal catalytic complexes, the first organocatalytic oxidation of silanes has been accomplished. Catalytic amounts of 2,2,2-trifluoroacetophenone, in combination with the green oxidant H2O2, lead to excellent to quant. yields in a short reaction time. A variety of alkyl, aryl, alkenyl, and alkynyl substituents can be tolerated, providing an easy, cheap, efficient, and practical solution to a highly desirable transformation.

Reaction of [Mn(OAc)(TPP)] (TPP = dianion of meso-tetraphenylporphine) with both HSSiiPr3 and HSSiPh3 in the presence of air gives the corresponding siloxide complexes, [Mn(OSiR3)(TPP)] (R = iPr, Ph), via silyl group transfer from S to O. The new compounds were fully characterized in solution and the solid state and represent rare examples of Mn(III) porphyrinates containing Lewis basic axial ligands. X-ray crystallog. analyses of both complexes reveal very short Mn-O bond distances consistent with the presence of a siloxide ligand. Investigations of the reaction pathway are consistent with initial reduction of [Mn(OAc)(TPP)] to [MnII(TPP)] by the silanethiol. Subsequent aerobic oxidation of the reaction mixture is proposed to generate a Mn(III) porphyrinate and the corresponding silanol, which combine to yield the observed siloxide complex. These findings stand in sharp contrast to those of iron(III) porphyrinates, where silanethiolate complexes are stable.

Hirano, Tomohiro published the artcileSyndiotactic-specific radical polymerization of N-isopropylacrylamide in toluene at low temperatures in the presence of silyl alcohols, Application In Synthesis of 17877-23-5, the publication is Polymer International (2012), 61(6), 966-970, database is CAplus.

The radical polymerization of N-isopropylacrylamide was carried out in toluene at low temperatures in the presence of silyl alcs., such as triethylsilanol. Poly(N-isopropylacrylamide) with a racemo dyad content of 75% was obtained at – 80° with a 4:1 triethylsilanol to monomer ratio loading. NMR anal. suggests that the mechanism for syndiotactic induction, in the presence of silyl alcs., may be similar to that observed with alkyl alcs. In this case, a 1:2 complex formation, via hydrogen bonding interactions, leads to the induction of syndiotactic specificity. Copyright © 2012 Society of Chem. Industry.
