Abstract
Novel cyclic di- and tetraester compounds made from the reaction of various unsaturated cyclic compounds with carboxylic acid anhydrides in the presence of oxygen are described. The process to make these novel ester compounds is preferably conducted at a temperature in the range from about 50.degree. to 150.degree. C. and in the presence of a catalyst. A transition metal borate catalyst is preferred. Such ester compounds are potentially useful plasticizers, lubricants, solvents and fuel additives.
