Abstract

Using titanium dioxide nanoparticles as recyclable catalyst for synthesis of 1-amidoalkyl-2-naphthols in solvent free condition

Author(s): Salman Rahmani*, Ali Amoozadeh

In this work a solvent-free and efficient method has been developed for the preparation of 1-amidoalkyl-2-naphthols from condensation of aldehydes with amides or urea and â-naphthol in the presence of nano-TiO2 under thermal solvent-free conditions. The advantages of this procedure are good yields, easy work-up and purification, mild reaction conditions and reusability of the catalyst.
