Cross coupling reactions catalyzed by (NHC)Pd(II) complexes

This review is focused on new developments reported during the last 3 years concerning the catalytic performances of in situ formed or preformed NHC–Pd(II) complexes (NHC: N-heterocyclic carbene) for cross-coupling reactions such as Heck–Mizoraki (often shortened to the Heck reaction), Kumada, Negishi, Suzuki–Miyaura (often shortened to the Suzuki reaction), Sonogashira and Hiyama couplings, and the Buchwald–Hartwig aminations, which are extremely powerful in the formation of C–C and C–heteroatom bonds.
