Patent number: 5633407Abstract: 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.degree. C. to about 150.degree. C. in a confined reaction zone wherein the molar ratio of protic material to base is 0:1 to about 5:1. In another embodiment, the substituted aromatic azo compounds are further reacted with a nucleophilic compound in the presence of a suitable solvent system, a suitable base and a controlled amount of protic material at a temperature of about 70.degree. C. to about 200.degree. C. in a confined reaction zone wherein the molar ratio of protic material to base is 0:1 to about 5:1 to produce a substituted aromatic amine.Type: GrantFiled: May 18, 1995Date of Patent: May 27, 1997Assignee: Flexsys America L. P.Inventors: Michael K. Stern, Brian K-M Cheng
