PROCESS FOR THE MANUFACTURE OF HALOGENATED PRECURSORS OF ALKENONES UNDER SPECIFIC CONDITIONS

摘要

The invention relates to a process for preparing a halogenated precursor of an alkenone, which comprises reacting a carboxylic acid halide with a vinyl ether in a liquid reaction medium under turbulent conditions. The invention also relates to a process for preparing an alkenone, by eliminating hydrogen halide from said precursor to form the alkenone.
