Abstract

PURPOSE: To obtain the titled two compounds in high yields, by the two steps of reacting an aromatic carboxylic acid chloride as a chlorine source with pivalic acid, distilling off all or part of the reaction product, and reacting the residue with a trichlorobenzene in the presence of a catalyst.
CONSTITUTION: An aromatic carboxylic acid chloride of the formula (R is H, Cl or COCl) is reacted with pivalic acid, and the pivaloyl chloride is then partly or wholly distilled from the resultant reaction product. The resultant residue is then reacted with a trichloromethylbenzene compound corresponding to the initially used aromatic carboxylic acid chloride in the presence of a Friedel- Crafts catalyst, e.g. FeCl3, to give the aimed aromatic carboxylic acid chloride.
EFFECT: High-purity products are sufficiently obtained from the inexpensive chlorine source.
USE: An intermediate raw material for medicines, agricultural chemicals, dyes and other industrial chemicals.
