Abstract
Process for preparing substituted alkylidene carboxylic acids, and especially a compound of formula ** (See formula) ** where R and R1 represent a member selected from the group consisting of hydrogen and levyalkyl; X is a member of the group consisting of hydrogen, halogen, levyalkyl or levialkoxyl and two X radicals of adjacent carbon atoms in the benzene ring can be combined to form a hydrocarbylene chain with 3-4 carbon atoms between their attachment points; m is an integer of value 1-4, and n is an integer of value 1-5; which consists of the reaction of a compound of formula ** (See formula) ** where R and R1 are as defined, and X2 represents a halogen, with a compound of formula ** (See formula) ** where X, m and n are as defined, in the presence of a metal halide.
