An Unusually Lower Barrier to Reductive Elimination of an 18-Electron μ3-Allyl(organo)nickel(II) Complex Than Those of a 16-Electron μ3-Allyl Counterpart and a 16-Electron μ1-Allyl Isomer

We report a novel finding that the coupling of allyl and aryl groups on Ni is much more facile in an μ³-allyl form with 18-electron configuration than in both a 16-electron μ³-allyl counterpart and a 16-electron μ¹-allyl isomer.This trend seems of particular relevance to the origin of some unique ligand and metal effects upon reactivity and selectivity in catalyses.
