摘要

以n -烷基-2-氯甲基苯并咪唑(即CH3, C2H5, CH2Ph) 1为原料，采用物理研磨法与硫脲反应，或采用乙醇、PEG-600等绿色溶剂，或采用微波辐照技术，建立了不同条件下合成n -烷基-2-硫甲基苯并咪唑2 (R=CH3, C2H5, CH2Ph)的绿色途径。

Synthesis of N-Alkyl-2-thiomethyl Benzimidazoles: A Green Approach

A green approach for the synthesis of N-alkyl-2-thiomethyl benzimidazoles 2 (R=CH3, C2H5, CH2Ph) under different conditions has been developed from N-alkyl-2-chloromethyl benzimidazole (i.e., CH3, C2H5, CH2Ph) 1 by reaction with thiourea by physical grinding, or by using green solvents like ethanol and PEG-600, or by using microwave irradiation technique.
