Copper(I) complexes of 8-(diphenylphosphanyl-oxy)-quinoline: Photophysics, structures and reactivity

Copper(I) complexes are studied for various potential applications due to their luminescence properties. However, issues have been identified regarding the stability of heteroleptic compounds. As a novel strategy, we propose to modify existing copper(I) complexes by introduction of molecular bridges between the different ligands. We report the synthesis and chemical properties of the complexes of 8-(diphenylphosphanyl-oxy)quinoline (POQ), a combination of a phosphine and a N-heterocycle with CuX (X = Cl, Br, I and SCN). The photophysical properties of the materials were studied. However, all four compounds were found to be labile in solution upon contact with trace amounts of water. Two POQ complexes and the decomposition products were identified as tetraphenyldiphosphoxane complexes with single crystal X-ray diffraction. We propose a design rule to prevent this behavior in future development steps.

Synthesis and characterization of iron and ruthenium complexes bearing P-N ligands based on 8-hydroxyquinoline

The synthesis of bidentate aminophosphine ligands (PNquin) based on 8-hydroxyquinoline is described. These ligands react with cis-Fe(CO) 4Br2 to give selectively octahedral complexes of the type cis,cis-Fe(PNquin)(CO)2Br2. There is only one isomer formed where the two CO and the two bromide ligands adopt a cis configuration. The reaction of [RuCp(CH3CN)3]PF 6 with PNquin ligands affords the halfsandwich complexes [RuCp(PNquin)(CH3CN)]PF6 in high isolated yields. Likewise, treatment of [Ru(η6-p-cymene)(μ-Cl)Cl] 2 with PNquin in the presence of AgCF3SO 3 affords halfsandwich complexes of the type [Ru(η6-p- cymene)(PNquin)Cl]CF3SO3. All ligands and complexes are characterized by NMR and IR spectroscopy. The X-ray structure of representative compounds is reported. In addition, the relative stability of isomeric structures and conformers of Fe(PNquin-Ph)(CO) 2Br2 is studied by means of DFT calculations.

Nucleophilic homogeneous hydrogenation by iridium complexes

Catalytic homogeneous hydrogenation of 7-methoxy-3-phenylchromone and other substrates was achieved in the presence of cationic iridium complexes and base as co-catalyst. Contrary to common alkene hydrogenation, which is inactivated by base, the hydrogena
