Preparation of α,β-unsaturated β-oxycarboxylic acid chlorides |
| abstract |
A process for the preparation of α,β-unsaturated β-oxycarboxylic acid chlorides of the formula I ##STR1## where R 1 is a C-organic radical, and R 2 and R 3 , independently of one another, are hydrogen or a C-organic radical, comprises carrying out the addition reaction of an enol derivative of the formula II ##STR2## with a compound of the formula IIIa, IIIb or IIIc ##STR3## and converting the resultant acid chloride of the formula ##STR4## into I by elimination of hydrogen chloride (HCl). |
