Compounds useful as plasticizers and the synthesis thereof are disclosed. In general, the invention includes mixed alkyl/aryl asymmetric cyclic diesters where the aryl and alkyl ester moieties are attached to a cyclic structure at vicinal carbons. The invention also includes synthetic processes of making such compounds. Blends of these asymmetric cyclic diesters with other plasticizers are demonstrated to be of use in plasticizing polymers.
