Preparation of halogenated aroylacetic acid esters |
| abstract |
A process for the preparation of a halogenated aroylacetic acid ester of the formula ##STR1## in which R is alkyl with 1-6 carbon atoms, n X and X 2 each independently is halogen, and n X 1 and X 3 each independently is hydrogen or halogen, comprising reacting a benzoyl chloride of the formula ##STR2## with dichloroethylene in the presence of anhydrous aluminum chloride to form the corresponding benzene trichloroethyl ketone, dehydrochlorinating the trichloroethyl ketone to form the corresponding benzene dichlorovinyl ketone, and treating the dichlorovinyl ketone with an alcoholate and then with an aqueous acid. The products are known intermediates for known antibacterials. |
