摘要：
An easy and efficient one-pot condensation method for the synthesis of substituted benzimidazoles from -phenylenediamines with aryl aldehydes using urea hydrogen peroxide (UHP) and I-2 in dimethylsulfoxide (DMSO) provides wide substrate scope with good to excellent yields and simple and quick isolation of the products.
