  Biscarbene Palladium(II) Complexes. Reactivity of Saturated Versus Unsaturated N-Heterocyclic Carbenes

  摘要：

  A series of designed palladium biscarbene complexes including saturated and unsaturated N-heterocyclic carbene (NHC) moieties have been prepared by the carbene transfer methods. All of these complexes have been characterized by H-1 and C-13 NMR spectroscopy as well as X-ray diffraction analysis, The reactivity of Pd-C-(saturated NHC) is distinct from that of Pd-C-(unsaturated NHC). The Pd-C-(saturated NHC) bonds are fairly stable toward reagents such as CF3COOH, AgBF4 and I-2, whereas Pd-C-(unsaturated NHC) bonds are readily cleaved under the similar conditions. Notably, the catalytically activity of these palladium complexes on Suzuki-Miyaura coupling follows the order: (sat-NHC)(2)PdCl2 > (sat-NHC)(unsat-NHC)PdCl2 > (unsat-NHC)(2)PdCl2.

  allyl, benzyl, 4-pentenyl] with (PhCN)2PdCl2, (PhCN)2PtCl2, [(CO)2RhCl]2, (Me2S)AuCl, [(CH3CN)4Cu]BF4, and AgBF4 provide the corresponding diaminocarbene complexes via carbene ligand transfer. The resulting Pd(II), Pt(II), Rh(I), and Au(I) carbene complexes are stable and were isolated. The Cu(I) and Ag(I) complexes readily undergo acid-induced MC cleavage to yield the imidazolidin-2-ylidinium salts. The
