Catalyst‐Free, Radical Tri‐ and Difluoromethylation of Isocyanides and <i>N</i>‐Arylacrylamides Using Rotating Magnetic Field and Metal Rods

Comprehensive Summary The pursuit of sustainable and environmentally benign synthetic methods continues to challenge organic chemists. Herein, we introduce a magnetoredox system for tri‐ and difluoromethylation of isocyanides and N ‐arylacrylamides using a rotating magnetic field and steel rods. This magnetoredox approach enables facile synthesis of functionalized phenanthridines and oxindoles without the need for catalysts and additives under mild conditions. Such a system potentially represents an attractive strategy for selective formation of bonds through multifaceted regulation of magnetic intensity, rotating frequency, and rod size.
