The regiochemistry of hydroformylation of alkenes can be controlled by use of bulky silyl groups attached to the alkene.Use of the t-butyldiphenylsilyl group leads to almost total regiocontrol and the method has been applied to the synthesis of aldols.

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