CuI-catalyzed amination of arylhalides with guanidines or amidines: A facile synthesis of 1-H-2-substituted benzimidazoles

Deng, Xiaohu,McAllister, Heather,Mani, Neelakandha S.

, p. 5742 - 5745 (2009)

(Figure Presented) CuI/L5 (N,N′-dimethylethylenediamine) proves to be an efficient catalyst system for the amination of arylhalides with guanidines. The same catalyst system is then successfully applied to the one-step synthesis of 1-H-2-aminobenzimidazol
