N,S-heterocyclic carbene complexes

Sheau W. Chien; Swee Kuan Yen; T. S. Andy Hor

This Review describes an important subclass of N-heterocyclic carbene complexes with thiazol-2-ylidenes ligands with only one exocyclic substituent on the thiazole ring. It highlights the synthetic, structural, and catalytic properties of these rapidly emerging complexes.

Unexpected coordination difference in geometric-isomerism between N,S- and N,N-heterocyclic carbenes in cyclometallated platinum(II)

The reaction of [Pt(II)(2-phenylpyridine)(acac)] and benzothiazolium bromide yields the N,S-heterocyclic carbene ligand trans to pyridyl while, surprisingly, a very similar N,N-heterocyclic carbene coordinates predominantly trans to the cyclometallated carbon.

Structures and Suzuki-Coupling of N-Heterocyclic Carbene Complexes of PdII with Coordinated Solvent and PPh3

Swee Kuan Yen; Lip Lin Koh; Han Vinh Huynh; T. S. Andy Hor

A series of mononuclear N,N-heterocyclic carbene (NNHC) complexes of PdII with mixed ligands of 1,3-dibenzylbenzimidazoly-2-ylidene and solvate (dimethyl sulfoxide, CH3CN, N,N-dimethylformamide, and pyridine) or PPh3 were prepared and characterized by X-ray single-crystal diffraction analysis. They are more active in the Suzuki–Miyaura coupling of selected aryl bromides than their N,S-heterocyclic carbene (NSHC) analogues.
