Mild Route To Convert SiH Compounds to Their Alkoxy Analogues

Alkoxysilanes, particularly ethoxysilanes, are widely used as cross-linkers for the moisture-induced, room-temperature vulcanization (RTV) of silicones. Karstedt’s platinum catalyst is shown to be effective at converting commercially available small hydrosiloxanes containing 1–8 SiH groups, and higher molecular weight telechelic and pendant hydrosiloxane polymers, into the corresponding alkoxy compounds. Kinetic studies demonstrated that …
