It is well known that the formation of silanols is always accompanied by generation of various side products. In this presentation, we will present a new methodology, in which silanes are converted to silanols in high yields using water as reactant and with Pt-nanoclusters as the catalyst. Our catalysts lead to selective formation of silanols, expect in some cases, where only trace amounts of side products are observed. 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. . The methodology is equally effective even in the presence of bulky groups. A comparative study was also undertaken to examine and compare 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 and the products were confirmed using NMR and Mass Spectroscopy.
