Treatment of cc,+dihydroxysilanes with trifluoroacetic acid in chloroform results in a 1,2-migration of the silyl group to give a-silyl aldehydes and ketones. The t-butyldimethylsilyl compounds can be isolated in high yields. Several workers' have reported that a,@-dihydroxytrimethylsilanes (1, R =
