Acetylsilane O-Silylcyanohydrins as Precursors to α-Silyl Ketones and β-Siloxy-N,N-bissilylenamines
Reduction of acetylsilane O-silylcyanohydrins gave β-amino-α-hydroxysilanes, which were diazotized to give α-silyl ketones.The addition of organolithium reagents to the cyanohydrins was accompanied by sequential C -> N and O -> N silyl group migrations.Silylation of the resulting lithium enolates afforded β-siloxy-N,N-bissilylenamines.

Synthesis and Consecutive Double Alkylation Reactions of (2-Siloxyallyl)silanes as the Synthetic Equivalent of Acetone α,α'-Dianion
(2-Siloxyallyl)silanes as the synthetic equivalent of tandem acetone α,α'-dianion, readily prepared by quenching of the enolate of α-(trimethylsilyl)acetone with chlorosilanes or by 1,3 C->O Si shift of bis(organosilyl)acetone, react with various electrop
