In this new methodology silanes are converted to silanols in high yields with little or no formation of disiloxanes using water with Pt-nanoclusters as the catalyst. The methodology is tolerant to several functional groups such as alkenes and alkynes, where it is noteworthy that in the presence of platinum metal complexes alkenes and alkynes are known to undergo hydrosilylation reaction. A comparative study is being done of the catalytic activity of platinum complexes with Pt nanoclusters. The nature of the true catalytic species was investigated via TEM, UV-vis and Poisoning Studies during the catalysis.
