Cis, cis muconic acid mononitrile and copper (II) salts thereof.

摘要

Phenol, catechol and orthobenzoquinone are converted to cis,cis-muconic acid mononitrile and its copper(II) salts by reaction with 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. The muconic acid mononitrile is useful as a monomer or comonomer and as an intermediate in the manufacture of substituted and unsubstituted 6-aminocaproic acids, caprolactams and polyamides.
