METHOD FOR PRODUCING CHLOROCARBOXYLIC ACID CHLORIDES

摘要

The invention relates to a method for producing chlorocarboxylic acid chlorides of formula (I) R<1>-CHCl-Y-COCl, wherein R<1> represents hydrogen or C1 to C20 alkyl for example and Y represents a saturated or a mono- or poly-olefinically unsaturated C2-C8 alkene chain for example, by reacting lactones with a chlorination agent in the presence of a urea compound.
