The reaction of (1) with NaON=CRR’ in the presence of KPF6 leads to the formation of the oximatoruthenium(II) complexes PF6 (2-5) in 70-90percent yield.Compound 5 (R=Me, R’=t-Bu) reacts with HN=CPh2 via ligand exchange to give PF6 (8).The azavinylidene complex 8 has also been prepared from the acetatoruthenium derivative PF6 (6), which can be obtained either from 1, CH3CO2Na and KPF6 or from treatment of 5 with an excess of CH3CO2H.The synthesis of the hexamethylbenzeneruthenium compounds PF6 (12-15) is achieved by the reaction of the hydrido(chloro)metal complexes (10, 11) with oximes HON=CR’2 and AgPF6.Nucleophilic addition of H- and CH-3 to the N=C carbon atom of + affords the uncharged imido compounds (16, 17).The cyclopentadienylruthenium complex (23) is prepared from either one of the imino derivatives BF4*0.5CH2Cl2 (22) or (25) on treatment with NaR (R=H, C5H5).Compound 25 reacts in toluene at room temperature by elimination of CH3CO2H to give the five-membered metallaheterocycle (26) which is an isomer of 23.The X-ray structural analysis of 5 reveals the presence of a O,N-bound oximato ligand and a cis position of the C6H6(PiPr3)Ru and t-Bu units at the N=C double bond.

The heating of a solution of [Ru(eta1-1,2-S2B6H9)(PPh 3)2(eta5-Cp)] 2 in CH2Cl 2 at reflux temperature afforded 1 in 59% yield. Compound 1 could be described as either a hypho nine-vertex {RuS2B6} cluster or a coordination compound of ruthenium which contains a bidentate eta2-dithiaborate cluster ligand; the latter description is preferred. Compound 2 contains an eight-atom hypho-type {1,2-S2B 6} cage bonded to the ruthenium atom of the {Ru(PPh3) 2(eta5-Cp)} unit by one sulfur atom and may be described as a compound of ruthenium coordinated eta1- to the dithiaborate cluster ligand.

Further reaction of 3 and PMePh 2 afforded another arachno {RhS2B6}cluster, [5-(eta6-MeC6H4Pri)-8-(PMePh 2)-arachno-5,4,6-RuS2B6H6], 4, in 25% yield.

Irradiation of 2 or Cp*Ru(CO)2CH3 (Cp* = C5Me5) in the presence of azobenzene or 4,4′-dimethylazobenzene affords orthometallated Cp*Ru(pap)(CO) (pap = (phenylazo)phenyl) and Cp*Ru(4,4′-dmpap)(CO) (4,4′-dmpap = (4,4′-dimethyl)(phenylazo)phenyl), respectively.From comparison of NMR data, their structures are similar to that of Cp*Fe(pap)(CO) the structure of which was determined by X-ray diffraction analysis.These and the corresponding molybdenum complex Cp*Mo(pap)(CO)2 afford 2,3-diphenylindole when reacted thermally or photochemically with diphenylacetylene.

Application of 92361-49-4, An article , which mentions 92361-49-4, molecular formula is C46H45ClP2Ru. The compound – Chloro(pentamethylcyclopentadienyl)bis(triphenylphosphine)ruthenium(II) played an important role in people’s production and life.

The dynamic behavior in solution of eight mono-hapto tetraphosphorus transition metal-complexes, trans-[Ru(dppm)2(H) (I·1-P4)]BF4 ([1]BF4), trans-[Ru(dppe)2(H)(I·1-P4)] BF4 ([2]BF4), [CpRu(PPh3) 2(I·1-P4)]PF6 ([3]PF6), [CpOs(PPh3)2(I· 1-P4)]PF6 ([4]PF6), [Cp*Ru(PPh3)2(I·1-P 4)]PF6 ([5]PF6), [Cp*Ru(dppe) (I·1-P4)]PF6 ([6]PF6), [Cp*Fe(dppe)(I·1-P4)]PF6 ([7]PF6), [(triphos)Re(CO)2(I·1- P4)]OTf ([8]OTf), and of three bimetallic Ru(mu, I·1:2-P4)Pt species [{Ru(dppm) 2(H)}(mu,I·1:2-P4){Pt(PPh 3)2}]BF4 ([1-Pt]BF4), [{Ru(dppe)2(H)}(mu,I·1:2-P 4){Pt(PPh3)2}]BF4 ([2-Pt]BF 4), [{CpRu(PPh3)2)}(mu,I· 1:2-P4){Pt(PPh3)2}]BF4 ([3-Pt]BF4), [dppm=bis(diphenylphosphanyl)methane; dppe=1,2-bis(diphenylphosphanyl)ethane; triphos=1,1,1- tris(diphenylphosphanylmethyl)ethane; Cp=I·5-C 5H5; Cp=I·5-C 5Me5] was studied by variable-temperature (VT) NMR and 31P{1H} exchange spectroscopy (EXSY). For most of the mononuclear species, NMR spectroscopy allowed to ascertain that the metal-coordinated P4 molecule experiences a dynamic process consisting, apart from the free rotation about the M-P4 axis, in a tumbling movement of the P4 cage while remaining chemically coordinated to the central metal. EXSY and VT 31P NMR experiments showed that also the binuclear complex cations [1-Pt]+-[3-Pt] + are subjected to molecular motions featured by the shift of each metal from one P to an adjacent one of the P4 moiety. The relative mobility of the metal fragments (Ru vs. Pt) was found to depend on the co-ligands of the binuclear complexes. For complexes [2]BF4 and [3]PF6, MAS, 31P NMR experiments revealed that the dynamic processes observed in solution (i.e., rotation and tumbling) may take place also in the solid state. The activation parameters for the dynamic processes of complexes 1+, 2+, 3+, 4+, 6 +, 8+ in solution, as well as the X-ray structures of 2+, 3+, 5+, 6+ are also reported. The data collected suggest that metal-coordinated P4 should not be considered as a static ligand in solution and in the solid state. A detailed solution and solid-state NMR dynamics study on mono- and bimetallic transition metal complexes, coordinating white phosphorus in I·1- P4 fashion, has revealed that this ligand is endowed of motions which depend on the nature of co-ligands and geometries around the metals. Activation parameters of the processes and X-ray crystal structures were also obtained (see figure). Copyright

Electric Literature of 32993-05-8. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II). In a document type is Article, introducing its new discovery.

Some pentamethylcyclopentadienyl ruthenium(II) diphosphine chloride complexes have been prepared by ligand exchange starting with the parent triphenylphosphine derivatives and their reactivities compared with those of the corresponding cyclopentadienyl compounds. The pentamethyl ligand causes a greater extent of asymmetric induction when the (R)-prophos and (R)-phenphos ligands are used as well as a higher lability of the stereochemistry at the stereogenic ruthenium centre. A shift of about 200 mV in the oxidation potential is caused by the substitution at the penta-hapto ligand. The order of basicity of the diphosphine ligands was also evaluated and was found to be consistent with previous determinations. The crystal structure of (eta5-C5Me)Ru{(S,S)-chiraphos}C1 shows a coordination around the ruthenium atom similar to that found for the (eta5-C5H5)Ru{(S,S)-chiraphos}Cl complex.

Treatment of Cp(PPh3)[P(OMe)3]RuC?CPh (2; Cp = eta5-C5H5) with PhN=C=S at room temperature affords the [2 + 2] cycloaddition product Cp(PPh3)[P(OMe)3]RuC=C(Ph)C-(=NPh)S (3a), containing a four-membered ring, and the neutral vinylidene phosphonate complex Cp(PPh3)[P(=O)(OMe)2]Ru=C=C(Ph)C(SH)=NPh (4a) in a 9:1 ratio. Formation of 4a results from an Arbuzov-like dealkylation reaction possibly after addition of PhN=C=S. The same reaction at 40 C affords a higher yield of 4a and Cp(PPh3)[P(OMe)3]RuC=C-(Ph)C(=S)N(R)C(=NR)S (5a; R = Ph) which results from addition of a second isothiocyanate to the four-membered ring of 3a. The reaction of 2 with PhCH2N=C=S at room temperature directly affords the six-membered-ring product 5b (R = CH2Ph). Trimerization of phenyl isothiocyanate is catalyzed by Cp(dppe)RuC=CPh (1?; dppe = Ph2PCH2CH2PPh2) in refluxing CH2Cl2. This catalytic reaction proceeds through a pathway in which the first two steps are the same as those observed in the reaction of 2a. An attempt to purify the precursor of the trimerization product gave the cocrystallization of 1? and (PhNCS)3 (8). The structures of 3a, 4a, 5b, and the cocrystallization product of 1? and 8 have been determined by single-crystal X-ray diffraction analysis.
