The reaction of [GeF4L2], L = dmso (Me2SO), dmf (Me2NCHO), py (pyridine), pyNO (pyridine-N-oxide), OPPh3, OPMe3, with Me3SiO3SCF3 (TMSOTf) and monodentate ligands, L, in a 1:1:1 molar ratio anhydrous CH2Cl2 formed the monocations [GeF3L3][OTf]. These rare trifluoro-germanium (IV) cations were characterised by microanalysis, IR, 1H, 19F{1H} and, where appropriate, 31P{1H} NMR spectroscopy. data ...

Abstract Dicationic bis‐quinolinium salts possessing different types of conjugation are presented in which the hetareniums separated by acetylenic or 1,4‐diethynylbenzene spacers. Cross‐conjugation is induced interconnections via 3‐positions heteroareniums, and realized 2,2/2,4/4,4‐interconnections. We also synthesized mixed cross‐conjugated/conjugated 2,3/4,3‐interconnected species. The determ...

The two major properties that underpin ionic liquids are tunability and the potential to create task-specific media. Together, these allow surpass roles long held by traditional molecular solvents. However, at elevated temperatures or under prolonged heating, structural components impart such decompose degrade. Dicationic pyridine salts present new opportunities extend functionality high becaus...

The synthesis of a range of rhodium(iii) and iridium(iii) half sandwich complexes with aryl dithiolato ligands of varying geometry and flexibility are reported. These include dinuclear [Cp*M(S-R-S)]2 complexes 3b and 4b, M = Rh, Ir; S-R-S = naphthalene-1,8-dithiolate (b) and four dinuclear complexes bearing bridging dithiolate ligands [(Cp*M)2(μ2-Cl)(μ2-S-R-S)]Cl 3c, 4c, 5b, 6b, M = Rh, Ir; S-R...

The synthesis and characterisation of three palladium complexes, involved in the homogeneous catalysis towards the CO-olefins coand ter-polymerisation reactions, are reported. The Pd (dpk·CH3OH) (CF3CO2)2 (1), (dpk = di(2-pyridyl) ketone) and Pd (dppp)(bipy) B(C6F5)4 2 (2), (bipy = 2,2’-bipyridine, dppp = 1,3-bis(diphenylphosphino)propane) compounds are examples of a neutral complex and of a di...

Dicationic sandwich complexes containing thiophene, 2-methylthiophene7 2,5-dimethylthiophene, and tetramethylthiophene react with ammonia to give salts of the formula [(ring)Ru(SC4R4NH2)lX where ring = CsMe6 or cymene. The thiophene, 2-methylthiophene, and 2,5-dimethylthiophene complexes undergo C-S cleavage to give iminium-thiolato derivatives. In the case of the 2,5-dimethylthiophene complex,...
