C-N bond formation reaction plays an important role in organic synthesis,which is often used in the synthesis of natural and synthetic bioactive compounds[1].In the past few decades,the C-H activation (including transition-metal catalyzed and metal-free catalyzed C-H activation) has become one of the most rapidly developing areas and remarkable achievements have been made in this filed[2-4].Very recently,the C-H activation strategy has been successfully used to C-N bond construction and has aroused great interest of chemists because of its atomic economy[5-6]Recently,it was found that aminocarbonylation could be realized through the activation of C-H bond of N,N-dimethylformamide (DMF),which is usually used as an excellent polar solvent and iigand[7-8].Herein,we would like to report an efficient method to construct C-N bonds by aminocarbonylation through C-H activation of DMF and 1H-benzo[d][1,2,3]triazole under metal-free condition.
