An efficient synthesis of 3-chlorohomoallyl alcohols. Zinc-promoted 2-chloroallylation of carbonyl compounds with 2,3-dichloropropene in an aqueous solvent system
摘要:
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.
The present invention provides a process for producing a propargylcarbinol compound of formula (I): ##STR1## where R.sup.1 and R.sup.2 are as defined herein. The process comprises reacting a haloallycarbinol compound of formula (II) with a base. The present invention also relates to a process for producing the haloallylcarbinol compound. The above propargylcarbinol compound is useful as an intermediate for agrochemicals, pharmaceuticals, perfumes, resin monomers, and the like.
