A dinuclear N-heterocyclic carbene (NHC) copper complex efficiently catalyzes azide-alkyne cycloaddition (CuAAC) "click" reactions. The ancillary ligand comprises two 4,5-dimethyl-1,3-thiazol-2-ylidene units and an ethylene linker. The three-step preparat

The development of atomically precise nanoclusters (APNCs) protected by organometallic ligands, such as acetylides and hydrides, is an emerging area of nanoscience. In principle, these organometallic APNCs should not require harsh pretreatment for activat

A series of new pyrene tagged nitrogen heterocyclic carbene copper (NHC-Cu) molecular complexes were synthesized and characterized by 1H- and 13C-NMR, high resolution ESI-mass spectrometry (HR-MS). The corresponding NHC-Cu complex was immobilized onto the surface of multi-walled carbon nanotubes (MWNTs) by using π-π stacking interaction, the noncovalent immobilization catalytic material MWNTs@NHC-Cu were characterized by FT-IR, XRD, XPS, thermogravimetry (TGA) and TEM. The new NHC-Cu complexes were tested both in the homogeneous phase and once immobilized onto multi-walled carbon nanotubes support for the azide-alkyne cycloaddition reaction. Both were active in the two-component click cycloaddition reaction of terminal alkynes and organic azides and three-component cycloaddition reaction that employs various terminal alkynes, NaN3 and organic halides with the advantage of excellent yields, low catalyst dosage, short reaction time. The MWNTs@NHC-Cu catalyst could be separated from the reaction system at the end of the reaction and reused in another catalytic cycle, but with loss of product yield.

Mononuclear copper complexes modified with tridentate tris(N-heterocyclic carbene) (triscarbene) ligands are synthesized. The structures of the copper-triscarbene complexes are characterized using X-ray crystallography, X-ray absorption near edge structur
