Perlite-SO3H nanoparticles: a novel and efficient catalyst for the synthesis of 14-aryl 14H-dibenzo[a,j]xanthenes under microwave conditions

Abstract

Perlite-SO3H nanoparticles efficiently catalyze the one-pot, two-component reaction of aryl aldehydes and 2-naphthol under solvent free microwave conditions to afford the cor­responding 14-aryl 14H-dibenzo[a,j]xanthene derivatives. The present approach offers several advantages such as shorter reaction times, good yields, low cost, and mild reaction conditions.
