Abstract

In a method or producing haloalkenone ethers by addition of a carboxylic acid halide to a vinyl ether and subsequent elimination of hydrogen halide, the improvement comprising carrying out the reaction in the absence of a base and/or in the presence of a stabilizer for the resulting alkenone, whereby higher yields of the desired alkenone product can be obtained.
