titleOfInvention | Process for the preparation of alpha, beta-unsaturated beta-oxycarboxylic acid chlorides |
abstract | Process for the preparation of alpha,beta-unsaturated beta-oxycarboxylic acid chlorides (beta-oxycarbonyl chlorides) of the formula I <IMAGE> in which R<1> represents C-organic radicals and R<2> and R<3> independently of one another represent hydrogen or C-organic radicals, characterized in that an enol derivative of the formula II <IMAGE> is subjected to an addition reaction with a compound IIIa, IIIb or IIIc <IMAGE> and the resulting acid chloride of the formula IV <IMAGE> is converted to I by elimination of hydrogen chloride (HCl).b |
