ZrOCl28H2O : an efficient and recyclable catalyst for the three-component synthesis of amidoalkyl naphtha’s under solvent-free conditions

Abstract EN

An efficient synthesis of amidoalkyl naphthols from the reaction of b-naphthol and various aromatic aldehydes and amides using ZrOCl2Æ8H2O, an environmentally friendly catalyst under a thermal solvent-free green procedure is described.

This simple protocol offers advantages such as shorter reaction times, simple work-up and excellent yield.

The catalyst ZrOCl2Æ8H2O can be reused.

The reusability of the catalyst has been studied for the synthesis of various amidoalkyl naphthols.
