An efficient synthesis of 3-chlorohomoallyl alcohols. Zinc-promoted 2-chloroallylation of carbonyl compounds with 2,3-dichloropropene in an aqueous solvent system

In the presence of metallic zinc, 2,3-dichloropropene has been found to react smoothly with a variety of carbonyl compounds in an aqueous solvent system to give the corresponding 3-chlorohomoallyl alcohols in excellent yields.
