Abstract Reaction of [Cu(N?CCH3)4]ClO4 with 3,8-dibromo-1,10-phenanthroline (BrphenBr) or 5,5?-dibromo-2,2?-bipyridine (BrbpyBr) and diphosphine ligands (±)-2,2?-bis(diphenylphosphino)-1,1?-binaphthalene (BINAP) or 9,9-dimethyl-4,5-bis(diphenylphosphino)-9H-xanthene (xantphos) in dichloromethane produced four mononuclear Cu(I)-diimine-diphosphine complexes in good yields. All structures are characterized by single crystal X-ray structure analysis, elemental analysis, electrospray ionization mass spectra, 1H NMR and 31P NMR spectra. All complexes are very stable to air and moisture in the solid state. The existence of soft P donors, the chelating effect of P and aromatic N atoms and the high-level protection of all the Cu(I) centers resulting from the close contact of bromodiimine and diphosphine ligands are suggested to be responsible for such stability. All complexes display moderate emission behavior in the solid state.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application In Synthesis of (9,9-Dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine), you can also check out more blogs about161265-03-8

Rh(I) and Rh(III) complexes of tricyclopentylphosphine (PCyp3), or its dehydrogenated variant PCyp2(eta2-C 5H7), partnered with wide-bite-angle chelating diphosphine ligands DPEphos and Xantphos have been prepared and characterized in solution and the solid state with the aim of studying their potential for reversible dehydrogenation of the PCyp3 ligand. The complexes fac-[Rh(kappa3-P,O,P-L){PCyp2(eta2-C 5H7)}][BArF4] (L = DPEphos, Xantphos) show pseudo-trigonal-bipyramidal structures in which the dehydrogenated phosphine alkene ligand acts in a chelating manner. Addition of H2 to fac-[Rh(kappa3-P,O,P-DPEphos){PCyp 2(eta2-C5H7)}][BAr F4] resulted in an equilibrium mixture of hydride and hydride-dihydrogen complexes, fac-[Rh(kappa3-P,O,P-DPEphos)(H) 2(PCyp3)][BArF4] and [Rh(kappa2-P,P-DPEphos)(eta2-H2)(H) 2(PCyp3)][BArF4], in which the DPEphos acts as a hemilabile ligand. For the more rigid Xantphos ligand two dihydride isomers, fac-[Rh(kappa3-P,O,P-Xantphos)(H) 2(PCyp3)][BArF4] and mer-[Rh(kappa3-P,O,P-Xantphos)(H)2(PCyp 3)][BArF4], are formed, which are also in equilibrium with one another. A van?t Hoff analysis of this mixture shows that enthalpically there is very little difference between the two geometries for this system, with the driving force for the preferred fac-geometry being entropic. Addition of MeCN to these hydrido complexes results in the central oxygen atom being displaced to form [Rh(kappa2-P,P-L)(PCyp 3)(H)2(MeCN)][BArF4], while removal of H2 from the hydrido complexes (under vacuum or on addition of a hydrogen acceptor) forms the Rh(I) complexes [Rh(kappa3-P,O,P-L) (PCyp3)][BArF4], which are characterized as having square-planar geometries with meridonial coordination of the respective chelating phosphines. Dehydrogenation of the PCyp3 ligand in these complexes to re-form the phosphine-alkene ligands does not occur, even under forcing conditions.

Three ruthenium complexes [RuCl(CTZ)(bipy)(P-P)]PF6 [P-P = 1,2-bis(diphenylphosphino)ethane (dppe-1), 1,4-bis(diphenylphosphino)butane (dppb-2) and 1,1?-bis(diphenylphosphino)ferrocene (dppf-3), bipy = 2,2?-bipiridine and clotrimazole (CTZ) 1-[(2-chlorophenyl)diphenylmethyl]-1H-imidazole] were synthesized. These complexes were characterized by a combination of elemental analysis, molar conductivity, infrared and UV?vis spectroscopy, 1H, 13C{1H} and 31P{1H} nuclear magnetic resonance techniques, cyclic voltammetry and mass spectroscopy. Bovine serum albumin binding constants, which were in the range of 1.30?36.00 × 104 M? 1, and thermodynamic parameters suggest spontaneous interactions with this protein by electrostatic forces due to the positive charge of the complexes. DNA interactions studied by spectroscopic titration, viscosity measurements, gel electrophoresis, circular dichroism, ethidium bromide displacement and reactions with guanosine and guanosine monophosphate indicated the DNA binding affinity primarily through non-covalent interactions. All complexes 1?3 were tested against the human carcinoma cell lines MCF-7 (breast), A549 (lung) and DU-145 (prostate) presenting promising IC50 values, between 0.50 and 14.00 muM, in some cases lower than the IC50 for the reference drug (cisplatin). The antimicrobial activity assays of the complexes provided evidence that they are potential agents against mycobacterial infections, specifically against Mycobacterium tuberculosis H37Rv.
