Pattanaik, Sandip published the artcileCobalt-Catalyzed Selective Synthesis of Disiloxanes and Hydrodisiloxanes, Recommanded Product: Triethylsilanol, the publication is ACS Catalysis (2019), 9(6), 5552-5561, database is CAplus.

Selective syntheses of sym. siloxanes and cyclotetrasiloxanes are attained from reactions of silanes and dihydrosilanes, resp., with H₂O, and the reactions are catalyzed by a NNN^HtBu Co(II) pincer complex. When phenylsilane was subjected to catalysis with H₂O, a siloxane cage consisting 12 Si and 18 O centers was obtained and remarkably the reaction proceeded with liberation of 3 equiv of H₂ (36 H₂) under mild exptl. conditions. Upon reaction of silane with different silanols, highly selective and controlled syntheses of higher order monohydrosiloxanes and disiloxymonohydrosilanes were achieved by Co catalysis. The liberated H₂ is the only byproduct observed in all of these transformations. Mechanistic studies indicated that the reactions occur via a homogeneous pathway. Kinetic and independent experiments confirmed the catalytic oxidation of silane to silanol, and further dehydrocoupling processes are involved in syntheses of sym. siloxanes, cyclotetrasiloxanes, and siloxane cage compounds, whereas the unsym. monohydrosiloxane syntheses from silanes and silanols proceeded via dehydrogenative coupling reactions. Overall these Co-catalyzed oxidative coupling reactions are based on the Si-H, Si-OH, and O-H bond activation of silane, silanol, and H₂O, resp. Catalytic cycles consisting of Co(II) intermediates probably are operative.

Langford, Vaughan S. published the artcileSelected ion flow tube studies of several siloxanes, HPLC of Formula: 597-52-4, the publication is Rapid Communications in Mass Spectrometry (2013), 27(6), 700-706, database is CAplus and MEDLINE.

People are using increasing amounts of siloxanes which ultimately end up in landfills, then in landfill gas and biogas digesters. Their presence poses difficulties for industries to use the energy content of landfill gas and biogas because the combustion process oxidizes Si to SiO₂ which in turn damages engine parts. Rapid, efficient, accurate methods are needed to quantify the presence of siloxanes. Selected ion flow tube mass spectrometry (SIFTMS), an emerging real-time technique, is used to monitor trace volatile compounds in air. Samples containing the trace volatile compounds are drawn into the flow tube and convected in a He stream. Chem. ionization reactions from mass-selected reagent ions with the volatile compounds occur. To quantify volatile compounds in the sample, the ion chem. of the reagent ion with each volatile must be known. Rate coefficients and product ion branching ratios were determined for dodecamethylpentasiloxane, decamethylcyclopentasiloxane, decamethyltetrasiloxane, octamethylcyclotetrasiloxane, triethylsilanol, tetramethylsilane, and hexamethyldisilazane. The ion/mol. reactions of these 7 Si-containing compounds were fast, occurring at or near the collision rate, allowing for low concentration detection. The very simple reaction chem. of proton transfer, electron transfer, and Me loss enables easy siloxane quantitation in landfill gas and biogas by SIFTMS. Copyright © 2013 John Wiley & Sons, Ltd.

Arzumanyan, Ashot V. published the artcileCopper-Catalyzed Oxidation of Hydrosilanes: A New Method for the Synthesis of Alkyl- and Siloxysilanols, Formula: C6H16OSi, the publication is Synlett (2018), 29(4), 489-492, database is CAplus.

A simple method for the preparation of silanols from the corresponding hydrosilanes is reported. The method employs a com. available oxidizing system based on CuCO ₃/ t-BuOOH _(aq)under relatively mild conditions (80 °C, atm. pressure) with acetonitrile as the solvent. Furthermore, we present a method that permits the Si-H group to be oxidized to a Si-OH group not only in triethylsilane, but also in bis(trimethylsiloxy)methylsilane, a siloxy derivative of hydrosilane. The products were isolated in gram amounts in yields of 61-73%.

Sharma, Hemant K. published the artcileSiloxymethylamines as aminomethylation reagents for amines leading to labile diaminomethanes that can be trapped as their [Mo(CO)₄] complexes, Computed Properties of 597-52-4, the publication is Chemistry – A European Journal (2016), 22(22), 7363-7366, database is CAplus and MEDLINE.

Compound Et₃SiOCH₂NMe₂ transfers the aminomethyl group, Me₂NCH₂ to R₂NH (R₂ = Et₂, PhMe, [Cr(η⁶-C₆H₅)(CO)₃]Me, PhH) giving previously unknown diaminomethanes, Me₂NCH₂NR₂ and, in the case of R₂ = PhH, the triamine Me₂NCH₂N(Ph)CH₂NMe₂. The diaminomethanes exhibit an unreported disproportionation to a mixture of (R₂N)₂CH₂, (Me₂N)₂CH₂, and Me₂NCH₂NR₂, which can be trapped as their [Mo(CO)₄(diamine)] complexes. Whereas PhMeNCH₂NMe₂ is a labile compound, the metal-substituted [(η⁶-C₆H₅)Cr(CO)₃]MeNCH₂NMe₂ is a stable material. The triamine Me₂NCH₂N(Ph)CH₂NMe₂ is unstable with respect to transformation to 1,3,5-triphenyltriazine, but is readily trapped as the bidentate-triamine Mo(CO)₄ complex. All metal complexes were characterized by single-crystal x-ray diffraction.

Gonzalez, Tania published the artcileCatalytic CO₂ hydrosilylation with [Mn(CO)₅Br] under mild reaction conditions, Name: Triethylsilanol, the publication is Polyhedron (2021), 115242, database is CAplus.

Carbon dioxide hydrosilylation with earth-abundant transition-metal catalysts is an attractive alternative for the design of greener and cost-effective synthetic strategies. Herein, simple [Mn(CO)₅Br] is an efficient precatalyst in the hydrosilylation of carbon dioxide with Et₃SiH under mild reaction conditions. Using THF as a solvent, triethylsilylformate Et₃SiCH(O)O was obtained in 67% yield after 1 h at 50°C and 4 bar of CO₂ pressure. The selectivity of the reaction was tuned by changing the solvent to a mixture of THF and toluene producing bis(triethylsilyl)acetal (Et₃SiO)₂CH₂ in 86% yield. The CO₂ hydrosilylation was also effective at room temperature and atm. pressure using either THF or the mixture THF/toluene as the solvent resulting in high Et₃SiH conversion (92%-99%) but with a decrease in the selectivity. Radical trapping experiments indicated the participation of radical species in the catalytic mechanism. To the best of our knowledge, this is the first report on CO₂ hydrosilylation catalyzed by transition-metal radical intermediates.

The ruthenacyclic carbamoyl complexes [RuX{2-NHC(O)C₅H₃NR}(CO)₂(NCMe)] (R = H and Me; X = Br and SC₆H₃-o,o-Me₂) are excellent catalysts for the hydrolysis of organosilanes, particularly towards primary silanes, generating H under ambient conditions within seconds. These complexes are structural mimics of the [Fe]-hydrogenase active site and like the natural enzyme, a labile ligand at the 6th coordination site is essential to the catalytic activity.

A convenient method for the selective synthesis of alkoxyhydrosiloxanes that bear SiH and SiOR² groups on the same silicon atom, R¹₃Si-O-SiR³_2-n(OR²)_nH (n = 0, 1, or 2), via a simple catalyst- and additive-free dealcoholization reaction between silanols and alkoxyhydrosilanes has been developed. These alkoxyhydrosiloxanes can be easily converted into Si(OR²)₃-containing siloxanes by zinc catalyzed alkoxylation and alkoxy-containing silphenylene polymers by platinum catalyzed hydrosilylation.

The reaction of CO₂ with Et₃SiH catalyzed by the nickel complex [(dippe)Ni(μ-H)]₂ (1) afforded the reduction products Et₃SiOCH₂OSiEt₃ (12%), Et₃SiOCH₃ (3%), and CO, which were characterized by standard spectroscopic methods. Part of the generated CO was found as the complex [(dippe)Ni(CO)]₂ (2), which was characterized by single-crystal x-ray diffraction. When the same reaction was carried out in the presence of a Lewis acid, such as Et₃B, the hydrosilylation of CO₂ efficiently proceeded to give the silyl formate (Et₃SiOC(O)H) in high yields (85-89%), at 80° for 1 h. Further reactivity of the silyl formate to yield formic acid, formamides, and alkyl formates was also investigated.
