A (Borylmethyl)silane Bearing Three Hydrolyzable Groups on Silicon: Synthesis via Iridium-Catalyzed C(sp3)-H Borylation and Conversion to Functionalized Siloxanes

An iridium-catalyzed C(sp3)-H borylation of X3SiMe (X = hydrolyzable group) was established. A trialkoxy(methyl)silane bearing sterically demanding neopentyloxy groups (X = neopentyloxy) underwent C-H borylation at the methyl group on silicon, giving (borylmethyl)tris(neopentyloxy)silane in 70% isolated yield. The choice of the hydrolyzable group X was the key to efficient and chemoselective C-H borylation; trialkoxy(methyl)silanes bearing sterically less demanding alkoxy groups (X = ethoxy, n-butyloxy, and isobutyloxy) suffered from C-H activation at the alkoxy groups, and trichloro(methyl)silane (X = Cl) failed to react. A trimethylsiloxy group could substitute the neopentyloxy groups of the borylated product by the reaction of trimethylsilanol in the presence of tetrabutylammonium fluoride.

Transesterification of Ethoxysilanes with Butyl Acetate in the Presence of Alkoxy Derivatives of Titanium

It was found for the first time that alkoxy derivatives of titanium of various structure act as effective catalysts in alkoxysilane transesterification with esters. Kinetic studies showed that both the catalytic activity of alkoxytitaniums and the reactivity of alkoxysilanes are structure-dependent. The preparative usefulness of titanium tetraalkoxides was demonstrated.

Catalytic Activity of Titanium Alkoxy Derivatives in Alcoholysis of Ethoxysilanes

Titanium tetraalkooxides, regardless of their structure, are effective catalysts for alcoholysis of ethoxysilanes. Titanium alkoxychlorides demonstrate the highest catalytic activity, whereas the catalytic activity of coordination-saturated titanium compounds is the lowest. The influence of the catalyst nature on its activity is analyzed.
