铜促进下腙的氧化胺化反应:1 H -吲唑和1 H -吡唑的合成

An efficient copper-promoted C(sp)—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.
