    Project supported by the National Natural Science Foundation of China(Nos. 21272149, 21302123), Innovation Program of Shanghai Municipal Education Commission(No. 14ZZ094) and Science and Technology Commission of Shanghai Municipality(No. 13ZR1416400).

An efficient copper-promoted C(sp2)-H bond amination was developed to afford 1H-indazoles and 1H-pyrazoles in moderate to excellent yields from easily accessible hydrazones. This process tolerated a variety of functional groups and afforded the corresponding 1H-indazoles and 1H-pyrazoles under mild conditions.

Key words: C-H activation, amination, indazole, nitrogen heterocycles, pyrazole
