Ligand displacement reactions of the complexes of the type(Ar)Ru(PPh 3)2(CH3CN)]PF6 {Ar=Cp* (1) and indenyl (2)} have been investigated with N3-terpyridine ligands, 4?-phenyl-2,2?:6?,2? terpyridine (phterpy), 4?-(4?-pyridyl)-2,2?:6?,2? terpyridine (pyterpy) and 1,4-bis(2,2?:6,6? terpyridin-4-yl) benzene (diterpy). The complexes [(Ar)Ru(PPh3)2(CH3CN)]PF6 {Ar=Cp* (1) and indenyl (2)} are reacted with these ligands to form stable complexes of the type [Cp*Ru(PPh3)(phterpy)]BF 4 (3), [Cp*Ru(PPh3)(pyterpy)]BF4 (4), [(eta5ind)Ru(PPh3)(phterpy)]PF6 (5), [(eta5ind)Ru(PPh3)(pyterpy)]PF6 (6), [(Cp*Ru(PPh3)}2 (diterpy)](BF4) 2 (7) and [(eta5ind)Ru(PPh3)} 2(diterpy)l(PF6)2 (8) where respective ligands are coordinated in a bidentate fashion. When these reactions are carried out with chloro analogues [Cp*Ru(PPh3)2Cl] (9) and [(eta5-ind)Ru(PPh3)2Cl] (10) with respective ligands viz. phterpy and pyterpy, a mixture of products are isolated including the complex type 3-6 and [RuCl(PPh3)2(N 3-phterpy)]PF6 (11) and [RuCl(PPh3) 2(N3-pyterpy)]PF6 (12) respectively. All these complexes have been characterized by spectral and analytical data.

Electric Literature of 32993-05-8, An article , which mentions 32993-05-8, molecular formula is C41H35ClP2Ru. The compound – Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II) played an important role in people’s production and life.

Reactions of [Ru{C=C(H)-1,4-C6H4C?CH}(PPh3)2Cp]BF4 ([1 a]BF4) with hydrohalic acids, HX, results in the formation of [Ru{C?C-1,4-C6H4-C(X)=CH2}(PPh3)2Cp] [X=Cl (2 a-Cl), Br (2 a-Br)], arising from facile Markovnikov addition of halide anions to the putative quinoidal cumulene cation [Ru(=C=C=C6H4=C=CH2)(PPh3)2Cp]+. Similarly, [M{C=C(H)-1,4-C6H4-C?CH}(LL)Cp]BF4 [M(LL)Cp?=Ru(PPh3)2Cp ([1 a]BF4); Ru(dppe)Cp* ([1 b]BF4); Fe(dppe)Cp ([1 c]BF4); Fe(dppe)Cp* ([1 d]BF4)] react with H+/H2O to give the acyl-functionalised phenylacetylide complexes [M{C?C-1,4-C6H4-C(=O)CH3}(LL)Cp?] (3 a?d) after workup. The Markovnikov addition of the nucleophile to the remote alkyne in the cations [1 a?d]+ is difficult to rationalise from the vinylidene form of the precursor and is much more satisfactorily explained from initial isomerisation to the quinoidal cumulene complexes [M(=C=C=C6H4=C=CH2)(LL)Cp?]+ prior to attack at the more exposed, remote quaternary carbon. Thus, whilst representative acetylide complexes [Ru(C?C-1,4-C6H4-C?CH)(PPh3)2Cp] (4 a) and [Ru(C?C-1,4-C6H4-C?CH)(dppe)Cp*] (4 b) reacted with the relatively small electrophiles [CN]+ and [C7H7]+ at the beta-carbon to give the expected vinylidene complexes, the bulky trityl ([CPh3]+) electrophile reacted with [M(C?C-1,4-C6H4-C?CH)(LL)Cp?] [M(LL)Cp?=Ru(PPh3)2Cp (4 a); Ru(dppe)Cp* (4 b); Fe(dppe)Cp (4 c); Fe(dppe)Cp* (4 d)] at the more exposed remote end of the carbon-rich ligand to give the putative quinoidal cumulene complexes [M{C=C=C6H4=C=C(H)CPh3}(LL)Cp?]+, which were isolated as the water adducts [M{C?C-1,4-C6H4-C(=O)CH2CPh3}(LL)Cp?] (6 a?d). Evincing the scope of the formation of such extended cumulenes from ethynyl-substituted arylvinylene precursors, the rather reactive half-sandwich (5-ethynyl-2-thienyl)vinylidene complexes [M{C=C(H)-2,5-cC4H2S-C?CH}(LL)Cp?]BF4 ([7 a?d]BF4 add water readily to give [M{C?C-2,5-cC4H2S-C(=O)CH3}(LL)Cp?] (8 a?d)].

CpRuCl(PPh3)2 reacts sequentially with bis(dimethylphosphino)methane (dmpm) to yield [CpRu(eta2-dmpm)(PPh3)]Cl (1) and then [CpRu(eta2-dmpm)(eta1-dmpm)]Cl (2a) from which hexafluorophosphate (2b) and trifluoromethanesulfonate (2c) salts can be obtained by metathesis. Attempts to synthesize CpRu(X)(eta1-dmpm)2 were largely unsuccessful and gave predominantly CpRu(X)(eta2-dmpm) (X = CN (3), C ? CPh (4)). In most instances, opening of the chelate ring in 2a did not occur on reaction with coordinatively unsaturated metal complexes and bi-and trimetallic products such as [CpRu(eta2-dmpm)(mu-dmpm)RuCpCl(PPh3)]Cl (5), [{CpRu(eta2-dmpm)(mu-dmpm)}2MLn]Cl 2 (MLn = PdCl2 (7), PtCl2 (8)) and [CpRu(eta2-dmpm)(mu-dmpm)RhCl(CO)(PPh3)] (CF3SO3) (9a) resulted. With Pt(C2H4)(PPh3)2, however, 2b afforded [CpRu(mu-dmpm)2Pt(PPh3)] PF6 (6). The structures of 1 and 6 were determined by X-ray crystallography. Copyright

Structural determinations and electrochemical properties in the series of multinuclear ferrocenyl-ethynyl complexes with formula [(eta5-C5R5)(P2)MII-C{triple bond, long}C-(fc)n-C{triple bond, long}C-MII(P2)(eta5-C5R5)] (fc = ferrocenyl; M = Fe(II), Ru(II), Os(II); R = H, CH3; P2 = Ph2PCH2CH2PPh2 (dppe), (C2H5)2PCH2CH2P(C2H5)2 (depe)) are reported. Complexes with more electron-rich ligand environment, such as [M(eta5-C5R5)P2] (R = CH3 and P2 = dppe, depe), were also prepared with regard to the understanding of electronic coupling mechanism. Structural determinations confirm that the ferrocenyl group is directly linked to the ethynyl linkage which is linked to the pseudo-octahedral [(eta5-C5R5)(P2)M] metal center. These complexes undergo sequential reversible oxidation events from 0.0 to 1.0 V referred to the Ag/AgCl electrode in anhydrous CH2Cl2 solution and the low-potential waves have been assigned to the two end-capped metallic centers. The magnitude of the electronic coupling between the two terminal metallic centers in the series of complexes was estimated by the electrochemical technique. Based on the correlation between the DeltaE1/2 values and the second redox potentials of the end-capping metallic centers in the series of complexes, a qualitative explanation for the difference of the electronic coupling is given.

The cyclic voltammogram shows RuIII/RuII (~1.1 V) and Ru IV/RuIII (~1.7 V) couples of the complexes 2 while Ru III/RuII (1.26 V) couple is observed only in 3 along with azo reductions in the potential window +2.0 to -2.0 V. DFT computation has been used to explain the spectra and redox properties of the complexes. In the oxidation reaction NMO acts as best oxidant and [RuCl(CO)(PPh 3)(SkappaRaaiNR)](PF6) (3) is the best catalyst. The formation of high-valent RuIV=O species as a catalytic intermediate is proposed for the oxidation process. Copyright
