摘要
Selective hydrolytic oxidation of organohydrosilanes was achieved with water in the presence of Pt-nanoparticle catalyst. The selectivity of the process was established by NMR analysis. In addition, various Pt-based catalysts were screened to compare the activity and selectivity with Pt-nanoparticles catalysis. The method was equally applicable to hydrosilanes bearing unsaturated functional groups, which led to corresponding silanols under mild reaction conditions without formation of any side products. Pt-nanoparticle catalysis was studied in details using UV-vis, TEM and mercury poisoning experiments during the transformation. Copyright (C) 2009 John Wiley & Sons, Ltd.
