A highly efficient, environmentally benign and reusable heterogeneous bentonite-gold nanohybrid catalyst was designed and synthesized. This heterogeneous catalyst could efficaciously catalyze the oxidation of organosilanes to silanols. The reaction is 98.7% atom economical and the products were obtained in excellent yield without the formation of disiloxanes as byproducts. The catalyst was also well applicable for the gram scale preparation of silanols.

Satoh, Yasushi published the artcileHighly selective synthesis of hydrosiloxanes by Au-catalyzed dehydrogenative cross-coupling reaction of silanols with hydrosilanes, Computed Properties of 17877-23-5, the publication is ACS Catalysis (2017), 7(3), 1836-1840, database is CAplus.

We report a highly selective synthesis of siloxane building blocks containing SiH₂or SiH functionalities. The system AuCl(PPh₃)/PPh₃ or AuCl(PPh₃)/PBu₃ catalyzed the reaction of trihydrosilanes with silanols giving SiH₂-containing siloxanes exclusively. On the other hand, a highly selective reaction of dihydrosilanes with silanols to afford SiH-containing siloxanes was achieved by simply changing the phosphine ligand to a bidentate one, xantphos. Usefulness of SiH₂-containing siloxanes was demonstrated by the synthesis of a trisiloxane, Et₃SiOSi(Ph)(H)OSi^tBuMe₂, and a pentasiloxane, Ph₂Si(OSiHPhOSiEt₃)₂, bearing SiH functionalities.

Kazmierczak, Joanna published the artcileNafion as effective and selective heterogeneous catalytic system in O-metalation of silanols and POSS silanols, Quality Control of 17877-23-5, the publication is Journal of Catalysis (2018), 95-103, database is CAplus.

Herein, we demonstrate the first use of Nafion as heterogeneous catalyst in O-metalation of compounds containing Si-OH moiety (silanols and POSS silanols). Our methodol. permits efficient and highly selective formation of Si-O-E bonds (E = Si, Ge, B) within mols., under mild conditions with excellent yields. This approach allows syntheses of various unsym. disiloxanes, germasiloxanes and borasiloxanes, as well as introduction of a wide range of functional groups into silsesquioxanes. It is worth noting that Nafion can be reused for further experiments and its catalytic activity in this process is well-maintained for more than 10 recycling steps, without a decrease in yield or selectivity.

Kucinski, Krzysztof published the artcileA Highly Effective Route to Si-O-Si Moieties through O-Silylation of Silanols and Polyhedral Oligomeric Silsesquioxane Silanols with Disilazanes, Quality Control of 17877-23-5, the publication is ChemSusChem (2019), 12(5), 1043-1048, database is CAplus and MEDLINE.

A simple and highly practical catalyst-free O-silylation of silanols with com. available disilazanes has been developed under mild conditions. In the case of polyhedral oligomeric silsesquioxane (POSS) silanols and some other silanols, it was necessary to use catalytic amounts of inexpensive Bi(OTf)₃ as addnl. catalyst. This efficient chlorine-free protocol involves the synthesis of a wide range of important organosilicon derivatives such as unsym. disiloxanes and functionalized silsesquioxanes.

Sun, Guang-Ri published the artcileCleavage of arylalkylsilanes by sodium amide in liquid ammonia, Product Details of C9H22OSi, the publication is Synlett (2000), 619-622, database is CAplus.

The aryl carbon-silicon bonds in arylalkyl monosilanes have been cleaved by sodium amide in liquid ammonia. Sub-stoichiometric amounts of amide effect complete cleavage of the aryl anion. Reactions were complete in just a few minutes at room temperature except when bulky alkyl groups are present (eg. triisopropylphenylsilane). In dialkyldiarylsilanes both aryl functions were rapidly cleaved with little selectivity when the aryl groups had different substituents. The influence of metallic cations was important (NaNH₂, KNH₂ >> LiNH₂ > Ca(NH₂)₂). Solvent and temperature were also studied.

Jeon, Mina published the artcileTransformation of Silanes into Silanols using Water and Recyclable Metal Nanoparticle Catalysts, Category: alcohols-buliding-blocks, the publication is ChemCatChem (2012), 4(4), 521-524, database is CAplus.

The highly selective and efficient transformation of organosilanes into silanols was achieved using readily available heterogeneous metal nanoparticle catalysts on an Al oxyhydroxide support [M/AlO(OH), M = Pd, Au, Rh, Ru, and Cu]. The transformation was performed under ambient conditions with H₂O. Among the catalysts studied, the Pd catalyst showed the highest activity; it was highly recyclable and applicable for large-scale reactions. The Pd catalyst was effective for a wide range of silanes, although small amounts of hydrogenated side products were formed in some cases for alkynyl silanes. The hydrogenation reaction was suppressed by using an O atm. or by using a gold catalyst. The Au catalyst could be reused at least ten times without any loss in activity.
