Platinum-catalyzed addition of dimethylsilylene to beta-methyl alpha,beta-unsaturated ketones: gamma-silylation forming 1-oxa-2-silacyclohex-5-enes.
The reaction of beta-methyl alpha,beta-unsaturated ketones with pentamethyldisilane in the presence of a platinum catalyst brought about silylation on the beta-methyl group giving high yields of oxasilacyclohexenes.
