摘要

Seven new air-and moisture-stable nickel complexes bearing flexible bulky NHC (N- heterocyclic carbene) ancillary ligands (NHC= IPr*, IPr* Tol, IPr* OMe, IPent) are reported. Using experimentally determined crystal structures, the steric environments of [Ni (NHC) CpCl] complexes were analyzed. A survey of their catalytic activity in Buchwald–Hartwig arylamination has been performed. In comparison to less sterically demanding analogues ...
