4-Silyl-5,6-dihydropyrans undergo remarkably selective [1,4]-Wittig rearrangements to give silylcyclopropanes in good yields. The selectivity is independent of the silyl group, but it is influenced by the electronic character of the migrating center. Elec

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.
