TRANSITION-METAL CATALYZED SILYLMETALATION OF ALLENES

Morizawa, Yoshitomi,Oda, Hiroji,Oshima, Koichiro,Nozaki, Hitosi

, p. 1163 - 1166 (2007/10/02)

Addition of PhMe2SiMgMe, (PhMe2Si)2Zn, or PhMe2SiAlEt2 to allenes proceeds in the presence of various transition-metal catalysts.Whereas copper catalyzed silylmagnesation of 1,2-cyclononadiene gives 1-dimethyl-phenylsilyl-1-cyclononene exclusively, palladium catalyzed silylalumination affords 3-dimethylphenylsilyl-1-cyclononene preferentially with high degrees of regioselectivity.
