Unexpected silicon group transfer in difunctional alkoxy silanes

During the hydrosilylation reaction of a difunctional silane with allyl glycidyl ether (AGE), two scrambled hydrosilylation products were produced in significant amounts. This scrambling is reaction condition dependent and has been observed in a few other examples. It appears to be the first such alkoxysilane transformation to occur under these conditions, although similar siloxane transformations have been documented. This also introduces a method of preparing certain organofunctional alkyldialkoxysilanes in high purities via hydrosilylation, where the close boiling rearrangement by-products are minimized.

Accelerated Anti-Markovnikov Alkene Hydrosilylation with Humic-Acid-Supported Electron-Deficient Platinum Single Atoms

The hydrosilylation reaction is one of the largest-scale applications of homogeneous catalysis, and Pt homogeneous catalysts have been widely used in this reaction for the commercial manufacture of silicon products. However, homogeneous Pt catalysts result in considerable problems, such as undesired side reactions, unacceptable catalyst residues and disposable platinum consumption. Here, we synthesized electron-deficient Pt single atoms supported on humic matter (Pt1@AHA_U_400), and the catalyst was used in hydrosilylation reactions, which showed super activity (turnover frequency as high as 3.0×107 h?1) and selectivity (>99 %). Density functional theory calculations reveal that the high performance of the catalyst results from the atomic dispersion of Pt and the electron deficiency of the Pt1 atoms, which is different from conventional Pt nanoscale catalysts. Excellent performance is maintained during recycle experiments, indicating the high stability of the catalyst.

Highly-active, graphene-supported platinum catalyst for the solventless hydrosilylation of olefins

Herein we report the development of the first graphene-supported platinum catalyst that has demonstrated exceptional catalytic activity and stability for hydrosilylation reactions of olefins (TOF 4.8 × 106 h-1, TON = 9.4 × 106). The catalyst also exhibited functional group tolerance over a broad range of industrially relevant substrates with minimal metal leaching. In addition, the catalyst system was successfully translated into a packed bed platform for continuous hydrosilylation reactions.
