A facile preparation of a high-load, soluble oligomeric alkyl cyclohexylcarbodiimide (OACC) reagent via ROM polymerization from commercially available starting materials is described. This reagent is exploited as a coupling reagent for esterification, amidation, and dehydration of carboxylicacids (aliphatic and aromatic) with an assortment of alcohols (aliphatic primary, secondary, and benzylic),
