Highly active higher coordinated copper(i)–N-heterocyclic chalcogenone catalysed click chemistry

Abstract

The tri-coordinated and tetra-coordinated copper(I) N-heterocyclic chalcogenone catalysed [3+2] cycloaddition reaction has been reported to understand the role of ancillary ligands and the coordination environment of the catalyst. A series...

Organo Chalcogenone-Triggered Luminescent Copper(I) Clusters for Light Emitting Applications

“…1-Isopropyl-3-(pyridin-2-yl)-imidazol-2-thione (L 1 ) was synthesized from corresponding imidazolium salts by treating it with elemental sulfur in the presence of K 2 CO 3 as previously reported. 56 1-Isopropyl-3-(pyridin-2-yl)-imidazol-2-selone (L 2 ) was synthesized according to the reported procedure. 57 L 1 was characterized by FTIR, 1 H NMR, and 13 C NMR techniques, powder X-ray diffraction, and single-crystal X-ray diffraction techniques.…”

Discrete copper(i) chalcogenones with metal–metal interaction

“…L 1 , L 2 , and L 3 were synthesized by following the previous literature. 35,36 L 1 and L 2 were treated with CuI in methanol to yield complexes 1 and 2 , respectively (Scheme 1). The complex 3 was synthesized by treating [Cu(CH 3 CN) 4 ]PF 6 salt with ligand L 3 in DCM (Scheme 2).…”

“…32,33 The coordination modes of heterocyclic selenoamides and thioamides with copper offer a variety of structurally diverse complexes from monomer to polymer networks with a variety of coordination modes; 34 both monodentate and bridging concerning the coordination of selenium or sulfur atoms. 35–37…”
