Replacement of a dimethyl amino group of the amidobis(amine) nickel(II) pincer complex (1), [(MeN2N)Ni-Cl], by a pyrrolidino group resulted in a new nickel(II) pincer complex (2), [(PyrNMeNN)Ni-Cl]. Complex 2 is an efficient catalyst for Kumada and Suzuki-Miyaura cross-coupling of nonactivated secondary alkyl halides, while complex 1 is largely inactive. The significant activity difference is tentatively attributed to a minimal structural difference, which leads to a more hemilabile ligand.
Tandem intramolecular carbolithiation-lithium/zinc transmetallation and applications to carbon-carbon bond-forming reactions
Yus, Miguel,Ortiz, Rosa

Lithium/zinc transmetallation with the cyclic organolithium intermediate 3 (prepared by intramolecular carbolithiation of the initially formed organolithium 2) gives the corresponding organozinc intermediate 5. Copper- or palladium-promoted SN2
