A new procedure for the allylation of aldehydes with allyltributyltin in the presence of 10 mol% dibutyltin dichloride and either an acid chloride or trimethylsilyl chloride has been developed. Homoallylic esters, carbonates, trimethylsilyl ethers, and alcohols were obtained in up to 99% yield. (C) 1996 Elsevier Science Ltd
