Dinuclear N-heterocyclic carbene copper(I) complexes

Magnesium amido N-heterocyclic carbene complexes.

Magnesium dications bind strongly to a tridentate anionic dicarbene ligand L = [N{CH(2)CH(2)(CNCHCHNMes)}(2)] forming dinuclear and trinuclear Mg complexes with some particularly short Mg-C bonds. Treatment of the proligand H(4)LCl(3) with three equivalents of methyl magnesium chloride or benzyl magnesium chloride affords Mg(3)(HL)Cl(6) in high yield. A suspension of in thf was heated to 80 deg...

Copper N-heterocyclic carbene (NHC) complexes as carbene transfer reagents.

A method is described that makes use of easily prepared, inexpensive copper synthons as N-heterocyclic carbene (NHC) transfer agents to generate catalytically relevant gold and palladium complexes.

Synthesis and Cytotoxicity of Dinuclear Silver (I)-N-Heterocyclic Carbene Complexes

Human colon cancer is the third most common and the fourth most frequent cause of cancer deaths worldwide [1]. The marketing chemotherapeutic drugs for the treatment of colon related cancer are Carboplatin, Levamisole, Miltefosine, Semustine and Floxuridine (Chart 1). The chart displays that most of the drugs are organic compounds. Among these, only Carboplatin is a metal based anticancer drug ...

Bent metal carbene geometries in amido N-heterocyclic carbene complexes.

Lithium(I) and uranium(VI) amido-tethered Bu(t)-substituted N-heterocyclic carbene (NHC) complexes exhibit very distorted metal-carbene bonds; the corresponding magnesium(II) and mesityl-substituted NHC uranium(VI) complexes are undistorted; the distortion does not affect the ligand binding strength, suggesting a dominance of electrostatic character in closed-shell electropositive metal-carbene...
