Deng, Xiaohu published the artcileCuI-catalyzed amination of arylhalides with guanidines or amidines: a facile synthesis of 1-H-2-substituted benzimidazoles, Product Details of C19H14N2, the publication is Journal of Organic Chemistry (2009), 74(15), 5742-5745, database is CAplus and MEDLINE.
CuI/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-amino-benzimidazoles through tandem aminations of 1,2-dihaloarenes in modest yields. This methodol. is also applicable for the preparation of 1-H or 1-substituted 2-aryl- or 2-alkyl-benzimidazoles.
