Abstract

 This study reports a new methodology for the efficient synthesis of TRISPHENOL compounds using the reaction of 2, 6-bis (hydroxymethyl) phenols with phenols under heterogeneous conditions. A SULFONATED REDUCED GRAPHENE OXIDE (RGO-SO3H) nanocatalyst was used to promote the reaction under SOLVENT-FREE CONDITIONS. A range of TRISPHENOL compounds were produced in the presence of this catalyst system in good to excellent yields. In the presence of this catalyst system, a less amount of phenol is required, which improves the environment through its capability in synthesis of TRISPHENOLs. The RGO-SO3H catalyst was reusable at least for 8 times in this process without a significant decrease in its catalytic activity.
