A Rapid and Facile Esterification of Na-Carboxylates with Alkyl Halides Promoted by the Synergy of the Combined Use of DMSO and an Ionic Liquid Under Ambient Conditions

Abstract

The synergy of the combined use of DMSO and an ionic liquid viz. (bbim)⁺Br⁻ has brought about a rapid and efficient esterification of sodium carboxylates with acyl and alkyl halides under ambient conditions in excellent isolated yields (90–95%) in short reaction times (12–40 min).
