Abstract

Abstract An unprecedented reductive dimerization of two carboxylic acids to produce ester derivatives by a combination catalyst involving InBr 3 and sulfuric acid is described. A sequential conversion of the in-situ formed ester to a symmetrical ether by indium-catalyzed deoxygenation of the ester with a hydrosilane in the same pot was also demonstrated.
