Rh(iii)-Catalyzed -fluoroalkenylation of N-nitrosoanilines with 2,2-difluorovinyl tosylates via C-H bond activation

Rh(iii)-Catalyzed -fluoroalkenylation of N-nitrosoanilines with 2,2-difluorovinyl tosylates has been realized. This reaction proceeded via chelation-assisted C-H activation, olefin insertion and -F elimination, leading to the synthesis of monofluoroalkenes with high Z-selectivity with respect to the olefin. This catalytic system is highly efficient over a broad range of substrates under mild and redox-neutral conditions.
