Reversing Conventional Site-Selectivity:Electrochemically Driven C(sp^(2))-H/C(sp^(3))-H Coupling with H_(2)Evolution
《CCS Chemistry》2023年第5期1086-1095,共10页Xuelian Zheng Pan Peng Cheng Huang Qingquan Lu 
support from the“1000-Youth Talents Plan”(Prof.Q.L.)and Wuhan University are greatly appreciated.
Sustainable and site-selective C–H functionalization is still a challenge because of the comparable properties of bonds of the same type.Here,an electrochemical C(sp^(2))–H/C(sp^(3))–H coupling with aryl iodides is...
