The pursuit of sustainable and environmentally benign synthetic methods continues to challenge organic chemists. Herein, we introduce a new redox system using a rotating magnetic field and steel rods. This magnetoredox approach enables tri- and difluoromethylation of isocyanides and N-arylacrylamides for facile synthesis of functionalized phenanthridines and oxindoles without the need for catalysts and additives under mild conditions. More details are discussed in the article by Li et al. on pages 155—160.
