Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), 32993-05-8.
(Indenyl)ruthenium complexes containing 1,1?-bis(diphenylphosphanyl)- ferrocene (dppf) and thiolato ligands: Synthesis, X-ray structure analysis, electrochemistry and magnetic studies
The reaction of [(Ind)Ru(dppf)Cl] (Ind = eta5-C 9H7) (2) with RSNa {R = Me, Et, Ph, Ph 2P(CH2)2) proceeds in MeOH to give [(Ind)Ru(dppf)(SR)] {R = Me (3), Et (4), Ph (5), Ph2P(CH 2)2 (7)}, as well as [(Ind)Ru(dppf)H] (6), in all cases except for R = Ph. This R-dependence of the product mixture was rationalised on a RS-/MeOH ? MeO-/RSH equilibrium involving the interaction of thiolate (RS-) with MeOH, and the relative nucleophilicities of RS- versus MeO-; 6 arose from beta-H elimination from an OMe derivative. Cyclic voltammetric measurements on 2, 3, 4 and 5, as well as the Cp (eta5-C5H5) and Cp* (eta5-C5Me5) analogues of 2, indicated that the formal oxidation potentials for [LRu(dppf)Cl] complexes {L = Ind (2), Cp (2A) and Cp* (2B)} occurred in the order Cp* < Ind < Cp, correlating with the more electron-donating groups lowering the oxidation potentials. EPR experiments performed on the one-electron oxidised forms of 3 and 5 indicated paramagnetic compounds with g values close to 2, while the two-electron oxidised forms of 3 and 5 were diamagnetic. All the complexes were characterised spectroscopically, and 5 and 6 also crystallographically. Wiley-VCH Verlag GmbH & Co.
