Treatment of 1-propenyltriphenylsilane with n-BuLi in THF-HMPA provides (triphenylsilyl)allylanion which is identical with an anion derived from 2-propenyltriphenylsilane and base. Generation of (triphenylgermyl)allylanion is also described. Addition of alkyl halides or carbonyl compounds to these anions gives the corresponding adducts regioselectively.
