摘要：

Treatment of 2- or 3-phenyl ketone arenesulfonylhydrazones with excess n-butyllithium in TMEDA at 50-60° for 2-3 h, followed by the addition of chlorotrimethylsilane, gives (1-arylallyl)silanes. Although the method has limitations, its simplicity and the availability of a companion procedure for the direct α-arylation of ketones provide desirable advantages. A number of electrophilic reactions are examined in an effort assess competitive benzylic resonance stabilization and CSi bond hyperconjugation in cyclic systems where stereoelectronic considerations also prevail. © 1979.
