Copper (II) reagent and preparation thereof

摘要

Muconic acid monoesters of alkanediols of 2-6 carbons and of phenol are prepared by copper (II) oxidative cleavage of phenols, catechols or orthobenzoquinones. The products are useful as comonomers in polyamides and other polymers. The alkanediol or phenol is introduced into the copper (II) reactant or catalyst.
