Abstract
Procedure for the preparation of phenoxyalkancarboxylic acids of the general formula I **(See formula)** where R1 signifies a nitro, amino, acylamino, lower alkoxy group or a halogen atom, R2 signifies hydrogen or a low molecular weight alcohol radical with 1 to 4 carbon atoms, and its esters with aliphatic, sky-aliphatic or araliphatics, or their salts with organic or inorganic bases, the α-4- (4'-halogenophenoxy) -phenoxypropionic acids of the formula being excluded, **(See formula)** characterized in that a) phenols of the general formula II are reacted **(See formula)** in which R1, has the above meaning, with alpha-halogenated fatty acids of the general formula III **(See formula)** in which R2 has the above meaning and Hal represents a halogen atom or its salts or esters with low molecular weight alcohols, in the presence of agents that separate hydrogen halide, and eventually the obtained phenoxyalkancarboxylic acid esters are saponified in an alkaline medium or the phenoxyalkane carboxylic acids obtained are esterified with aliphatic, cycloaliphatic or araliphatic alcohols, or b) carboxylic acids of the general formula I in which R1 signifies the nitro group, or its esters or salts, and in 4-amino-phenoxy acids are reduced -carboxylic compounds thus obtained or their derivatives, optionally acylate the amino group by treatment with acylating agents, and optionally before or after acylation, a carboxylic acid ester group is saponified in alkaline medium or a carboxylic acid is esterified with aliphatic, cycloaliphatic alcohols or araliphatic or c) esters of the general formula IV are transesterified **(See formula)** wherein R1 and R2 have the above meanings and R3 signifies a lower alcohol radical, by reaction with higher boiling point aliphatic, cycloaliphatic or araliphatic alcohols.
