The reaction of tris (2-thienyl)phosphine (1) with dirhodium(II) acetate in a 9:1 refluxing toluene / acetic acid mixture for 2 h leads to the formation of two metalated compounds. The structure of one of them contained two new orthometalated phosphines in a head-to-head arrangement, and, surprisingly, the metalated thiophene rings, but not the nonmetalated ones, were rearranged to a 3-thienyl structure. Both types of dirhodium compounds were assessed in a catalytic alpha-diazo ester transformation.

Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. I hope my blog about is helpful to your research. Computed Properties of C8H12BrN

Reaction of [Re2(CO)9(NCMe)] with tri(2-thienyl)phosphine (PTh3) in refluxing cyclohexane affords three substituted dirhenium complexes: [ Re2(CO)9(PTh 3)] (1), [Re 2(CO)8(NCMe)(PTh3)] (2), and [Re2(CO)8(PTh3)2] (3). Complex 2 was also obtained from the room-temperature reaction of [Re2(CO) 8(NCMe)2] with PTh3 and is an unusual example in which the acetonitrile and phosphine ligands are coordinated to the same rhenium atom. Thermolysis of 1 and 3 in refluxing xylene affords [Re 2(CO)8(mu-PTh2)(mu-eta1: kappa1-C4H3S)] (4) and [Re 2(CO)7(PTh3)(mu-PTh2)(mu-H)] (5), respectively, both resulting from carbon-phosphorus bond ceavage of a coordinated PTh3 ligand. Reaction of [Re2(CO) 10] and PTh3 in refluxing xylene gives a complex mixture of products. These products include 3-5, two further binuclear products, [Re2(CO)7(PTh3)(mu-PTh2)(mu- eta1:kappa1-C4H3S)] (6) and [Re 2(CO)7(mu-kappa1:kappa2- Th2PC4H2SPTh)(mu-eta1:kappa1 C4H3S)] (7), and the mononuclear hydrides [ReH(CO) 4(PTh3)] (8) and fran-[ReH(CO)3(PTh 3)2] (9). Binuclear 6 is structurally similar to 4 and can be obtained from reaction of the latter with 1 equiv of PTh3. Formation of 7 involves a series of rearrangements resulting in the formation of a unique new diphosphine ligand, Th2PC4H2SPTh. Reaction of [Mn2(CO)10] with PTh3 in refluxing toluene affords the phosphine-substituted product [Mn2(CO) 9(PTh3)] (10) and two carbon-phosphorus bond cleavage products, [Mn2(CO)6(mu-PTh2)(mu- eta1:eta5-C4H3S)] (11) and [Mn2(CO)5(PTh3)(mu-PTh2)(mu- eta1:eta5-C4H3S)] (12). Both 11 and 12 contain a bridging thienyl ligand that is bonded to one manganese atom in a eta5-fashion. The molecular structures of eight of these new complexes were established by single-crystal X-ray diffraction studies, allowing a detailed analysis of the disposition of the coordinated ligands.

Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 19977-51-6, molcular formula is C8H12BrN, introducing its new discovery. Formula: C8H12BrN

Reaction of [Ru3(CO)9{mu3-eta1,kappa1,kappa2-PhP(C6H4)CH2PPh}] (1) with tri(2-thienyl)phosphine (PTh3) in refluxing THF afforded [Ru3(CO)9(PTh3)(mu-dpbm)] (3) {dpbm = PhP(C6H4)(CH2)PPh} and [Ru3(CO)6(mu-CO)2{mu-kappa1,eta1-PTh2(C4H2S)}{mu3-kappa1,kappa2-Ph2PCH2PPh}] (5) in 18% and 12% yields, respectively, while a similar reaction with tri(2-furyl)phosphine (PFu3) gave [Ru3(CO)9(PFu3)(mu-dpbm)] (4) and [Ru3(CO)7(mu-eta1,eta2-C4H3O)(mu-PFu2){mu3-eta1,kappa1,kappa2-PhP(C6H4)CH2PPh}] (6) in 24% and 27% yields, respectively. Compounds 2 and 4 are phosphine adducts of 1 in which the diphosphine ligand is transformed into 1,3-diphenyl-2,3-dihydro-1H-1,3-benzodiphosphine (dpbm) via phosphorus-carbon bond formation. Cluster 5 results from metalation of a thienyl ring, the cleaved proton being transferred to the diphosphine. Carbon-phosphorus bond cleavage of a PFu3 ligand is observed in 6 to afford a phosphido-bridge and a furyl fragment, the latter bridging in a sigma,pi-vinyl fashion. The molecular structures of 3, 5 and 6 have been determined by X-ray diffraction studies.

The new clusters [Ru3(CO)9(mu-dppf){P(C 4H3E)3}] (1, E = O; 2, E = S) have been prepared from the Me3NO-induced decarbonylation of [Ru 3(CO)10(mu-dppf)] in the presence of PFu3 (E = O) and PTh3 (E = S), respectively. Upon thermolysis in benzene, the major products are the cyclometalated clusters [(mu-H)Ru3(CO) 7(mu-dppf){mu3-(C4H3E) 2P(C4H2E)}] (3, E = O; 4, E = S). This thermolytic behavior is in marked contrast to that previously noted for the analogous bis(diphenylphosphino)methane (dppm) complexes [Ru3(CO) 9(mu-dppm){P(C4H3E)3}], in which both carbon-hydrogen and carbon-phosphorus bond activation yields furyne- and thiophyne-capped clusters. The crystal structures of 1, 3 and 4 are presented and reveal that phosphine migration has occurred during the transformation of 1,2 into 3,4, respectively. The possible relation of the observed reactivity to the relative flexibilities of the diphosphine ligands is discussed. Density functional calculations have been performed on the model cluster [Ru 3(CO)9(mu-Me4-dppf){P(C4H 3O)3]}], and these data are discussed relative to the ground-state energy differences extant between the different isomeric forms of this cluster. The dynamic NMR behavior displayed by the metalated thienyl ring in cluster 4 has also been investigated by computational methods, and the free energy of activation for the “windshield wiper” motion of the activated thienyl moiety determined.

Thermal transformations of tris(2-thienyl)phosphine (PTh3) at low-valent ruthenium cluster centers: Part I. Carbon-hydrogen, carbon-phosphorus and carbon-sulfur bond activation yielding Ru3(CO)8L{mu-Th2P(C4H2S)}(mu-H) (L = CO, PTh3), Ru3(CO)7(mu-PTh2)2(mu3-eta2-C4H2S), Ru4(CO)9(mu-CO)2(mu4-eta2-C4H2S)(mu4-PTh) and Ru5(CO)11(mu-PTh2)(mu4-eta4-C4H3)(mu4-S)

Reaction of Ru3(CO)12 with tris(2-thienyl)phosphine (PTh3) in CH2Cl2 at room temperature or in THF in the presence of a catalytic amount of Na[Ph2CO] furnishes the carbonyl substitution products Ru3(CO)11(PTh3) (1), Ru3(CO)10(PTh3)2 (2), and Ru3(CO)9(PTh3)3 (3). Heating 1 in toluene affords the cyclometalated cluster Ru3(CO)9{mu-Th2P(C4H2S)}(mu-H) (4) resulting from carbonyl loss and carbon-hydrogen bond activation, and both 4 and the substituted derivative Ru3(CO)8{mu-Th2P(C4H2S)}(PTh3)(mu-H) (5) resulted from the direct reaction of Ru3(CO)12 and PTh3 at 110 C in toluene. Interestingly, thermolysis of 2 in benzene at 80 C affords 5 together with phosphido-bridged Ru3(CO)7(mu-PTh2)2(mu3-eta2-C4H2S) (6) resulting from both phosphorus-carbon and carbon-hydrogen bond activation of coordinated PTh3 ligand(s). Cluster 6 is the only product of the thermolysis of 2 in toluene. Heating cyclometalated 4 with Ru3(CO)12 in toluene at 110 C yielded the tetranuclear phosphinidine cluster, Ru4(CO)9(mu-CO)2(mu4-eta2-C4H2S)(mu4-PTh) (7), resulting from carbon-phosphorus bond scission, together with the pentaruthenium sulfide cluster, Ru5(CO)11(mu-PTh2)(mu4-eta4-C4H3)(mu4-S) (8), in which sulfur is extruded from a thiophene ring. All the new compounds were characterized by elemental analysis, mass spectrometry, IR and NMR spectroscopy, and by single crystal X-ray diffraction analysis in case of clusters 4, 6, 7, and 8. Cluster 4 consists of a triangular ruthenium framework containing a mu3-Th2P(C4H2S) ligand, while 6 consists of a ruthenium triangle containing eta2-mu3-thiophyne ligand and two edge-bridging PTh2 ligands. Cluster 7 exhibits a distorted square arrangement of ruthenium atoms that are capped on one side by a mu4-phosphinidene ligand and on the other by a 4e donating mu4-eta2-C4H2S ligand. The structure of 8 represents a rare example of a pentaruthenium wing-tip bridged-butterfly skeleton capped by mu4-S and mu4-eta4-C4H3 ligands. The compounds 4, 6, 7, and 8 have been examined by density functional theory (DFT), and the lowest energy structure computed coincides with the X-ray diffraction structure. The hemilabile nature of the activated thienyl ligand in 4 and 6 has also been computationally investigated.

Oxidative-addition of the N-H bond of saccharin (sacH) to a triosmium centre: Synthesis, structure and reactivity of Os3(CO)10(mu-H)(mu-sac) This paper is dedicated to Professor Kazi Azam on the occasion of his retirement. A talented scientist, true gentleman, and inspiration to generations of students at Jahangirnager University.

Saccharin (sacH) is a widely-used sweetener and consequently its chemistry has been extensively studied, but here we report a rare example of its reactivity towards a multinuclear metal centre. Lightly-stabilized Os3(CO)10-n(NCMe)n (n = 1, 2) react with sacH to afford Os3(CO)10(mu-H) (mu-sac) (1) in which the sac ligand bridges an osmium-osmium vector via nitrogen and the carbonylic oxygen (mu-N,O). The reactivity of 1 towards monodentate phosphines, PR3 (R = Ph, Th, Fu), has been investigated. Carbonyl substitution affords both mono- and bis-phosphine substituted derivatives Os3(CO)9(PR3) (mu-H) (mu-sac) (2) and Os3(CO)8(PR3)2(mu-H) (mu-sac) (3) respectively. In the mono-substituted derivatives, the phosphine occupies an equatorial position on the osmium that is directly bonded to the carbonylic oxygen of saccharinate, while in the bis-(phosphine) substituted derivatives the second phosphine is bound to the remote osmium also occupying an equatorial site. In all complexes the saccharinate ligand remains in the bidentate N,O coordination mode thus playing a directing spectator role in these reactions.
