ABSTRACT:
Phenol, catechol and orthobenzoquinone are converted to muconic acid mononitrile by reaction with a copper(II)-ammonia reagent. The copper(II)-ammonia reagents can be prepared by the reaction of cuprous chloride with oxygen or air in liquid ammonia or in ammonium hydroxide or in pyridine followed by addition of ammonia or ammonium hydroxide. Muconic acid mononitrile is hydrogenated to 6-aminocaproic acid, which can be cyclized to caprolactam.
