Cathodic coupling of ketones with 3-(trimethylsilyl)allyl alcohols has been found to give trimethylsilyl substituted 1,3-diols with high diastereoselectivity, whereas that with 2-(trimethylsilyl)allyl alcohols afforded homoallylic alcohols through the Peterson elimination of intermediately formed trimethylsilyl substituted 1,4-diols.

aldehydes into alkyne-zirconocene complexes provides configurationally pureallyl alcohols in a one-pot procedure. In the case of unsymmetrical alkynes, the regioselectivity of the insertion process is high for terminal alkynes. With trimethylsilyl-substituted alkynes the regioseectivity is low. The insertion of chiral aldehydes into the symmetrical oct-4-yne-zirconocene complex provides the Cram isomer as
