In an article, published in an article, once mentioned the application of 92361-49-4, Name is Chloro(pentamethylcyclopentadienyl)bis(triphenylphosphine)ruthenium(II),molecular formula is C46H45ClP2Ru, is a conventional compound. this article was the specific content is as follows.Safety of Chloro(pentamethylcyclopentadienyl)bis(triphenylphosphine)ruthenium(II)
Cationic ruthenium dihydrogen complexes of the form [(eta-C5H5)Ru(L)(L?)(eta2-H 2)]BF4 (L = CO, L? = PCy3 (1a), PPh3 (2a), PMe2Ph (3a), PMe3 (4a) have been prepared by protonation of the corresponding neutral hydrides. Carbonyl free derivatives such as [(eta-C5H5)Ru(P P?)(eta2-H2)]BF4 (P P? = 1,2-bis(dimethylphosphino)ethane (dmpe) (5a), (1,1-dimethyl-2,2-diphenylphosphino)ethane (dmdppe) (6a), (R)-(+)-1,2-bis(diphenylphosphino)propane ((R)-prophos) (8a), bis(PPh3) (9a)) were similarly prepared. Pentamethylcyclopentadienyl analogues [(eta-C5Me5)Ru(P P?(eta2-H2)]BF4 (P P? = dmdppe (7a), (PPh3J2 (10a)) and [(eta-C5Me5)Ru(CO)(PCy3)(eta 2-H2)]BF4 (11a) have also been prepared. Identification of these species as dihydrogen complexes is based upon observation of substantial H-D coupling (22-32 Hz) in the 1H NMR spectra of the HD analogues, prepared by protonation of the corresponding deuterides. In every case studied in detail, the kinetic product of the protonation reaction is the dihydrogen complex, but an intramolecular isomerization occurs to give variable amounts of the transoid dihydride form at equilibrium. The composition of the equilibrium mixture and the rate at which the equilibrium is obtained depend upon the ligand environment. Facile rotation of the coordinated H2 ligand in the ruthenium complexes is established by the study of chiral complexes. The coordinated H2 in these complexes is substantially activated toward heterolytic cleavage. In the case of 5a, the measured pKa is 17.6 (CH3CN), with the dihydrogen form deprotonated more rapidly than the dihydride.
