ChemInform Abstract: A Convenient Synthesis of Protected and Free Homoallylic Alcohols: Catalytic Use of Dibutyltin Dichloride in the Allylation of Aldehydes with Allyltributyltin

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.
