0.01 mol-% Zinc(II) salts catalyze the reaction between acetals and acid halides to provide haloalkyl ethers in near-quantitative yield in 1 - 4 h. The solutions of haloalkyl ethers can be utilized directly in reactions in which the presence of the ester byproduct does not interfere. Excess carcinogenic haloalkyl ether is destroyed on workup.
