PdII complexes of donor-functionalized heterocyclic carbene ligands have been synthesized through a route involving carbene transfer from AgI carbene precursors. The Ag complexes undergo facile reaction with PdCl2(MeCN)2 to yield Pd(C∧OPh)2Cl2 (3a), Pd(C∧OOMe)2Cl2 (3b), and Pd(C∧N)2Cl2 (3c) (C∧OPh = 3-methyl-1-phenacylimidazolin-2-ylidene, C∧OOMe = 3-methyl-1-(methylacetyl)imidazolin-2-ylidene, C∧N = 3-methyl-1-picolylimidazolin-2-ylidene), from which [Pd(C∧OOMe)2(MeCN)2][BF4]2 (4b) and [Pd(C∧N… CONTINUE READING
