Three‐component solventless Strecker synthesis of α‐aminonitriles catalysed by a renewable sulfonated nanoporous carbon catalyst (CMK‐5‐SO₃H)

Abstract

The one‐pot three‐component synthesis of a variety of α‐aminonitriles has been studied using a catalytic amount of a sulfonic acid‐functionalized ordered nanoporous carbon catalyst, CMK‐5‐SO3H, at room temperature under solvent‐free reaction conditions. The heterogeneous catalyst could be readily isolated from the reaction mixture and reused at least ten times without significant loss in activity. A clean, rapid and simple method for the preparation of α‐aminonitriles using the recoverable CMK‐5‐SO3H catalyst is described.
