The Activity of Magnesium/Aluminum ‘Memory Effect’ Reconstructed Hydrotalcites in the Microwave-Assisted Synthesis of 2-Benzimidazolethiol and Its Alkylated Derivatives
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
