Process for preparing substituted aromatic azo compounds

摘要

A process for preparing substituted aromatic azo compounds is provided which comprises contacting a nucleophilic compound and an azo containing compound in the presence of a suitable solvent system, and reacting the nucleophilic compound and the azo containing compound in the presence of a suitable base and a controlled amount of protic material at a temperature of about 10 DEG C. to about 150 DEG C. in a confined reaction zone wherein the molar ratio of protic material to base is 0:1 to about 5:1.
