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 […]
Si-Im/HSO4(1-methyl-3-(3-(trimethoxysilyl) propyl) imidazolium hydrogen sulphate functionalized Copper oxide nanoparticles(CuO NPs )as a novel supporting ionic liquid was prepared and characterized by FT-IR spectroscopy, FE-SEM, XRD, TGA, and EDX techniques. It was used as a recyclable catalyst for the one-pot, three-component synthesis of 1, 4- dihydro Pyrano [2, 3-c] pyrazoles derivatives. The results showed that the […]
