摘要：

A new silica supported piperazine sulfosalicylic acid catalyst has been synthesized and explored for the synthesis of 2-aryl benzimidazoles. The catalyst is found to be highly efficient and recyclable. The new catalytic system is found to exhibit excellent yields of 2-aryl benzimidazoles and moderate to good yields of 2-heteroaryl and 2-alkyl benzimidazoles.
