    摘要: Process for synthesizing a chemical, in particular an agriculturally or pharmaceutically active compound, including: a first step comprising reacting a carboxylic acid halide with a vinyl ether to prepare a halogenated precursor of an alkenone; a second step comprising eliminating hydrogen halide from such precursor to form an alkenone, preferably by thermolysis under specific conditions; and a third step which uses the formed alkenone as a building block to synthesize the chemical. First step may be done in a liquid reaction medium comprising an alkenone or a halogenated alkenone precursor, or in a liquid reaction medium in turbulent state, specifically by creation of gas bubbles of the carboxylic acid halide herein. Second step may include a flash thermolysis, vacuum thermolysis, thermolysis under stripping with inert gas, and/or a thermolysis at a temperature from >90° C. to 120° C. Third step preferably comprises reacting the alkenone with a nitrogen-containing compound.

    摘要: A method of producing a halogen alkenone ether by attaching carboxylic acid halogenides or carboxylic acid anhydrides to a vinyl ether. According to the invention the method is carried out in the presence of an onium salt of a carbonic acid which can be regenerated. The resulting product is obtained in high yields. Alternatively, pyridine which is substituted by one, two or three C1-C3 alkyl groups or other onium salts can be used.
