The catalytic application of bismuth(III) coordination polymer has been reported. Dinuclear bismuth(III) chalcogenone complexes [(L1)2BiCl2(μ2-Cl)]2 (1), [(L2)2BiBr2(μ2-Br)]2 (4), 2D layered bismuth(III) thione complex [{(L2)BiCl2(μ2-Cl)}2]∞ (2), and 1D chain [(L1)Bi(Br)(μ2-Br)2.CH3CN]∞ (3)...

Phosphine coordinated copper(I)-N-heterocyclic carbene complexes have emerged as an efficient material in catalysis and light-emitting applications. In this study, a gentle and sustainable approach to the copper(I)-carbene phosphine complexes is reported through an efficient C=Se activation protocol. The complexes [(Py^NHC)Cu(PPh 3 ) 2 ]X, X = BF 4 (1), ClO 4 (2), PF 6 (3) and OTf (4); Py^NHC = 3isopropyl-1-(pyridin-2-yl)-imidazol-2-ylidene, and [(Py^NHC)Cu(PPh 3 )(X)], X = Br (5) and I ( 6) have been synthesized by treating 1-isopropyl-3-(pyridin-2-yl)-imidazole-2-selone with corresponding copper(I) precursors and triphenylphosphine. In this synthetic strategy, N-heterocyclic carbene gets transferred from N-heterocyclic selone through a C=Se bond cleavage reaction to form copper(I) complexes within five minutes at room temperature. In addition, the mechanism responsible for the C=Se bond cleavage reaction has been fully investigated. These reactions are not sensitive to moisture and oxygen.
