AbstractSelective 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 © 2009 John Wiley & Sons, Ltd.
