Rh(iii)-Catalyzed switchable C–H monoalkenylation and dialkenylation of 2-(1H-pyrazol-1-yl)pyridine with alkenes via rollover cyclometalation
Autor: Bolin Zhu, Haifang Meng, Fang Yang, Mengjia Chen, Chen Chen
Publikováno v: Organic Chemistry Frontiers. 8:773-777
We have developed a Rh(III)-catalyzed C–H alkenylation reaction of the N,N-bidentate chelating compound 2-(1H-pyrazol-1-yl)pyridine with alkenes via rollover cyclometalation. Mono- and dialkenyl-substituted 2-(1H-pyrazol-1-yl)pyridines could be sel
