Visible light photocatalytic cross-coupling and addition reactions of arylalkynes with perfluoroalkyl iodides have been developed. Through slight modification of the reaction conditions, reactions that are selective for the preparation of...

A series of luminescent bis(isocyanoborato) rhenate-(I) phenanthroline complexes with the general formula of cis,trans-[Re(CO) 2 (CNBR 3 ) 2 (phen)]K (R = C 6 F 5 and C 6 H 5 ) have been designed and synthesized. The solutions of these complexes exhibit MLCT phosphorescence. Detailed anion titration study showed that the emission intensity of bis(isocyanotriphenylborato) complex in CH 3 CN/H 2 O solution would be significantly decreased in the presence of cyanide anion, while such a change would not be observed in the presence of other anions including F

The successful generation of perfluoroalkyl radical (Rf) through photoredox catalysis has inspired us to investigate the preparation of various organolfuorine species. In this work, visible light-induced photocatalytic reactions for the...

A series of cyano-bridged homotrinuclear Re(I) complexes with the general formula of {diphosphine, or two carbonyl ligands; X = triphenylphosphine or carbonyl ligand} and the corresponding mononuclear complex analogues were synthesized. The structures of most of the trinuclear Re(I) complexes have been determined by X-ray crystallography. The relative orientations of peripheral to central Re(I) units in these structures vary considerably. The photophysical properties of these trinuclear Re(I) complexes have been examined. Except for the trinuclear Re(I) complex with Br 2 phen ligand, all the other triads display orange to red photoluminescence derived from the 3 MLCT [dπ(Re) → π*(phen)] origin of the central Re(I) unit, suggestive of efficient energy transfer between the peripheral chromophores and the central unit. In addition to the efficient energy transfer processes between the Re(I) chromophores in these trinuclear complexes, the ability of the [NC−Re−CN] bridging ligands for electronic coupling between the rhenium metal centers is evidenced by ca. 0.2−0.3 V separation of the two rhenium metal-based oxidation potentials of the chemically equivalent peripheral units.

C 54H44Cl2Cu2N2P2,m onoclinic, C12/c1(no. 15 Source of materialThe title compound was obtained by the reaction of CuCl and PPh 3 (molar ratio 1:1) in the presence of isoquinoline (1 ml) in the mixed solution of CH 3OH (5 ml) and CH2Cl2 (5 ml) for 4hours at ambient temperature. The insoluble residues were removed by filtration, and the filtrate was evaporated slowly at room temperature for about one week to yield yellow crystals. Crystals suitable for single crystal X-ray diffraction investigation were extracted directly from the sample as prepared.
