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), HPLC of Formula: C41H35ClP2Ru.
The syntheses of the chloro complexes [RU(eta5-C 5R5)Cl(L)] (R = H, Me; L = phosphinoamine ligand) (1a-d) have been carried out by reaction of [(eta5-C5H 5)RuCl(PPh3)2] or {(eta5-C 5Me5)RuCl}4 with the corresponding phosphinoamine (R,R)-1,2-bis((diisopropylphosphino)amino)cyclohexane), R,R-dippach, or 1,2-bis(((diisopropylphosphino)amino)ethane), dippae. The chloride abstraction reactions from these compounds lead to different products depending on the starting chlorocomplex and the reaction conditions. Under argon atmosphere, chloride abstraction from [(eta5-C5Me 5)-RuCl(R,R-dippach)] with NaBAr?4 yields the compound [(eta5-C5Me5) Ru(kappa3P,P?-(R,R)-dippachp)][BAr?4] (2b) which exhibits a three-membered ring Ru-N-P by a new coordination form of this phosphinoamine. However, under the same conditions the reaction starting from [(eta5-C5Me5)RuCl(dippae)] yields the unsaturated 16 electron complex [(eta5-C5Me 5)Ru(dippae)][BAr?4] (2d). The bonding modes of R,R-dippach and dippae ligands have been analyzed by DFT calculations. The possibility of tridentate P,N,P-coordination of the phosphinoamide ligand to a fragment [(eta5-C5Me5)Ru]+ is always present, but only the presence of a cyclohexane unit in the ligand framework converts this bonding mode in a more favorable option than the usual P,P-coordination. Dinitrogen [(eta5-C5R 5)Ru(N2)(L)][BAr?4] (3a-d) and dioxygen complexes [(eta5-C5H5)Ru(O 2)(R,R-dippach)][BPh4] (4a) and [(eta5-C 5Me5)Ru(O2)(L)][BPh4] (4b,d) have been prepared by chloride abstraction under dinitrogen or dioxygen atmosphere, respectively. The presence of 16 electron [(eta5-C 5H5)Ru(R,R-dippach)]+ species in fluorobenzene solutions of the corresponding dinitrogen or dioxygen complexes in conjunction with the presence of [BAr?4]- gave in some cases a small fraction of [Ru(eta5-C5H5) (eta6-C6H5F)][BAr?4] (5a), which has been isolated and characterized by X-ray diffraction.
