Abstract

Abstract : A simple, rapid, green, and highly efficient method for the synthesis of substituted trisphenols is described from the reaction of 2, 6-bis (methylol) phenols (BMP) and different substituted phenols in the presence of a nanosilica supported dual acidic ionic liquid (NSSDAIL), supported 1-methyl-3-(4-sulfobutyl) imidazolium hydrogen sulfate, as catalyst under solvent-free conditions. This reaction allowed us to prepare some new and known derivatives of substituted trisphenols. This procedure is a clean and environmentally friendly approach to prepare different 2, 6-bis(2-hydroxy benzyl) phenol derivatives that offers many advantages, including short reaction times and high yield of the products, use a non corrosive and reusable catalyst and solvent-free conditions.
