Copper-Catalyzed Double C–S Bonds Formation via Different Paths: Synthesis of Benzothiazoles from N-Benzyl-2-iodoaniline and Potassium Sulfide
摘要:
A new, highly efficient procedure for the synthesis of benzothiazoles from easily available N-benzyl-2-iodoaniline and potassium sulfide has been developed. The results show copper-catalyzed double C-S bond formation via a traditional cross-coupling reaction and an oxidative cross-coupling reaction.

A simple, one-pot and copper-catalyzed coupling reaction for the construction of 1,2-disubstituted benzimidazole derivatives is described. Low-cost copper salt and weak base K3PO4 were utlized in this reaction. A variety of 1,2-disubstituted benzimidazoles were obtained in moderate to excellent yields.
