Mineral Oil Shale Part Based-Support as Heterogeneous Catalyst for Organophosphorus Synthesis Assisted by Ultrasounds

Abstract

A new heterogeneous catalyst has been developed based on moroccan oil shale raw matter. This new support was used in the α-hydroxyphosphonates synthesis by Pudovik pathway using dialkylphosphites and carbonyls compounds. The transformation was performed by using oil shale-based catalyst under room temperature and by ultrasound-assisted synthetic approach. Both approaches have been found to be efficient in this organophosphorus synthesis. The reaction was carried out with a high yield in dry media, the catalyst is separated easily and reused several times without losing its activity.
