Abstract:

A combined experimental/theoretical study of Ni pincer complexes with a bridgehead pyrimidine-based NHC and arylphosphino side arms revealed unique features about stepwise C–H activation, ethylene insertion into the Ni–H bond of an isolated complex followed by ethyl migration with C–C^NHC coupling, and an unprecedented C–P bond activation affording via PPh₂ migration a Ni^II complex with a terminal phosphanido ligand and a novel C–C^NHC–P pincer ligand.
