A mechanistic investigation of the Pd-catalyzed cross-coupling betweenN-tosylhydrazones and aryl halides

“…[137][138][139][140] This versatile palladium-catalyzed cross-coupling between amines and aryl or vinyl halides is widely used and new applications are reported frequently. [141][142][143][144][145][146][147][148][149][150] The reaction mechanism is thought to involve oxidative addition of the aryl halide to Pd(0), coordination of the aniline, deprotonation by base, and reductive elimination of the new C-N bond regenerating the Pd(0) catalyst. [151][152][153] Improved understanding of the reaction and observation of the intermediates during this reaction will aid the further development of catalysts and ligands, as well as provide a thorough understanding of substrate effects, allowing optimization of every reaction component.…”
