heterogeneous base for the alkylation reactions. An efficient and practical methodology for the microwave-assisted synthesis of 2-benzimidazolethiol from 1,2-benzenediamine and carbon disulfide using reconstructed hydrotalcite is described. The corresponding mono- and dialkylated derivatives of 2-benzimidazolethiol were obtained generally in good to excellent yields after short reaction times. Reconstructed
摘要 描述了一种高效实用的方法,可利用重构的水滑石从1,2-苯二胺和二硫化碳进行微波辅助合成2-苯并咪唑硫醇。在短的反应时间之后,通常以良好或优异的产率获得2-苯并咪唑硫醇的相应的单和二烷基化的衍生物。重构水滑石被证明是用于烷基化反应的有效且可重复使用的异质碱。 描述了一种高效实用的方法,可利用重构的水滑石从1,2-苯二胺和二硫化碳进行微波辅助合成2-苯并咪唑硫醇。在短的反应时间之后,通常以良好或优异的产率获得2-苯并咪唑硫醇的相应的单和二烷基化的衍生物。重构水滑石被证明是用于烷基化反应的有效且可重复使用的异质碱。
