Ultrasound mediated synthesis of α-aminophosphonates and 3,4-dihydropyrimidin-2-ones using graphene oxide as a recyclable catalyst under solvent-free conditions

Abstract

Graphene oxide functions as an effective and reusable carbocatalyst for the multicomponent synthesis of α-aminophosphonates and 3,4-dihydropyrimidinones under solvent-free conditions using ultrasonic irradiation.
