参考标题:Cui-Catalyzed Amination Of Arylhalides With Guanidines Or Amidines: A Facile Synthesis Of 1-H-2-Substituted Benzimidazoles 作者:Xiaohu Deng,Heather Mcallister,Neelakandha S. Mani |发布日期:2009.8.7 摘要: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-Amino-Benzimidazoles Through Tandem Aminations Of 1,2-Dihaloarenes In Modest Yields. This Methodology Is Also Applicable For The Preparation Of 1-H Or 1-Substutituted 2-Aryl- Or 2-Alkyl-Benzimidazoles
