Suzuki Coupling Reaction- Mechanism, Steps and Advantages

WebApr 13, 2024 · A tridentate bis-NHC Pd complex, based on caffeine, was studied for its catalytic activity. This complex displayed a high catalytic activity in the Suzuki–Miyaura and Mizoroki–Heck cross-coupling reactions of aryl halides. The Sonogashira cross-coupling was also investigated but reveals a fast plateauing of … The mechanism of the Suzuki reaction is best viewed from the perspective of the palladium catalyst. The catalytic cycle is initiated by the formation of an active Pd catyltic species, A. This participates in the oxidative addition of palladium to the halide reagent 1 to form the organopalladium intermediate B.
