摘要：

Mono and dinuclear palladium-NHC complexes of 1,3-bis(2-pyridyl)imidazolin-2-ylidene (py(2)im) ligand, such as [Pd(py(2)im)(2)](PF6)(2) (2) [Pd2Cl2(Py(2)im)(2)](PF6)(2) (3), and [PdCl2(py(2)im)] (4) were synthesized by carbene transfer method using trinuclear Cu(I)-NHC complex, [Cu-3(Py(2)im)(3)](PF6)(3) (1). Also addition of PPh3 to the solution of 3 or in the reaction medium of 1 with PdCl2 resulted in a mononuclear bisphosphine complex [PdCl(PPh3)(2)(Py(2)im)](PF6) (5) which can also be prepared using trans-[PdCl2(PPh3)(2)] (6) and [Cu(PPh3)(2)(Py(2)im)](PF6) (7) as precursors. In addition a mono nuclear complex [Hg(py(2)im)(2)](PF6)(2) (8) was synthesized through carbene transfer from 1. (C) 2019 Elsevier Ltd. All rights reserved.
