摘要：

We report on synthesis of 1,2-disubstituted benzimidazoles in pure water using nanostructured pyrophosphate Na2CaP2O7. Our findings showed that this heterogeneous catalyst exhibited high catalytic activity and high selectivity in the synthesis of 1,2-disubstituted benzimidazoles from direct cyclocondensation of aromatic aldehydes with substituted o-diaminoarene in pure water. The salient benefits of this method rely on various factors namely: a simple procedure, mildness of the reaction conditions, short reaction times, operational simplicity, high chemoselectivity, low cost and recyclability of the catalyst.
