Abstract

1495472 Phenylene diacetic acid dialkyl esters and their preparation DYNAMIT NOBEL AG 4 March 1975 [7 March 1974] 9008/75 Heading C2C The invention comprises a process for the preparation of phenylenediacetic acid dialkyl esters of the general Formula I in which X represents hydrogen or chlorine and R represents a C 1-6 alkyl radical, which comprises reacting a xylylene dichloride of Formula II with carbon monoxide and an alcohol of formula in the presence of a basic reagent and a metal carbonyl as catalyst. The invention also comprises the dimethyl esters of 3,4,5,6-tetrachloro-o-phenylene diacetic acid, 2,4,5,6 - tetrachloro - m - phenylene diacetic acid and 2,3,5,6-tetrachloro-p-phenylene diacetic acid per se.
