One-pot synthesis of amidoalkyl naphthols using NaHSO4 center dot SiO2 as an efficient and recyclable heterogeneous catalyst
An efficient synthesis of amidoalkyl naphthols using silica supported sodium hydrogen sulphate as heterogeneous catalyst under a thermal solvent-free green procedure is described. This simple protocol offer advantages such as shorter reaction times, simple work-up, excellent yield, and recovery and reusability of the catalyst.
