SO3H-Carbon derived from glycerol: An efficient and recyclable catalyst for smooth and regioselective azidolysis of oxiranes in water

Abstract

A series of β -hydroxyazides were effectively synthesized from the regioselective ring opening of oxiranes by azide anion in presence of glycerol-based sulfonic acid functionalized carbon as a novel reusable heterogeneous catalyst in H 2 O achieving good yields (80-98%). The workup procedure was simple, and the catalyst could be reused over five times without losing its catalytic activity and selectivity.
