Synthetic Route of 246047-72-3. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 246047-72-3, Name is (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium. In a document type is Article, introducing its new discovery.

Cycloisomerization is an atom economic procedure that converts dienes and enynes into cyclic molecules. To date, cycloisomerization between enamides and silylalkynes has not been explored. We found that N-acyl-N-vinyl-2-silylalkynylaniline derivatives undergo a cycloisomerization in the presence of a well-defined ruthenium hydride to give a 2,3-disubstitued indole. The vinyl and silylmethyl substituents on the 2- and 3-positions of the indole can be easily converted to other functional groups.

A new tridentate ligand, 2-furyl (m-aminophenylenimine)methyl ketone (FAMK), was synthesised from m-phenylenediamine and furanglyoxal. Its metal complexes of the general formula [M(FAMK)X2H2O], where M = Mn(II), Co(II) and Ni(II) and [M(FAMK)X3], where M = Rh(III), Ru(III) and Ir(III) have been prepared. On the basis of chemical analyses, magnetic moment measurements, IR and electronic spectra, an octahedral geometry of the ligand around the metallic ions has been suggested. The fungicidal activities of the ligand and its metal complexes have also been studied.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 10049-08-8 is helpful to your research., Synthetic Route of 10049-08-8

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.10049-08-8, Name is Ruthenium(III) chloride, molecular formula is Cl3Ru. In a Article，once mentioned of 10049-08-8, name: Ruthenium(III) chloride

Complexes of pyridine-2-carboxaldehyde thiosemicarbazone (HPAT) with Cu(II), Ni(II), Zn(II), Cd(II), Hg(II), Co(III), Fe(III), Ru(III), In(III) and Al(III) have been prepared and characterized through chemical analyses, electronic and infrared spectral studies and magnetic and conductance measurements.The ligand shows three types of coordination behaviour.In the complexes , (NO3)2.C2H5OH, .C2H5OH, and .C2H5OH it acts as a neutral tridentate ligand coordinating through the ring nitrogen, azomethine nitrogen and the sulphur atom, while in BF4 and Cl, it behaves as a monobasic tridentate ligand coordinating through the same donor atoms.In the complexes , Cl and Cl3 it acts as a bidentate ligand coordinating only through the ring nitrogen and azomethine nitrogen.Monomeric octahedral or dimeric chlorine-bridged, approximately octahedral structures are proposed for these complexes.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.name: Ruthenium(III) chloride, you can also check out more blogs about10049-08-8

37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer, molecular formula is C12H12Cl4Ru2, belongs to ruthenium-catalysts compound, is a common compound. In a patnet, once mentioned the new application about 37366-09-9, Formula: C12H12Cl4Ru2

The migration of a phenyl group from phosphorus to the coordinated ruthenium center in complexes (eta6-arene)[eta2-Ph 2PC(R)=C(R?)O]RuCl, 2 [arene = 1,3,5-Me3C6H3 or C6Me6; R = H or Me; R? = But], occurs in methanol at reflux. The reaction is favored by the addition of KOAc and affords selectively the stable phosphinito enolato derivatives (eta6-arene)[eta2-Ph-(MeO)PC(R)=C(R?)O]RuPh. In contrast, the reaction of complexes 2 with methanol and K2CO3 preserves the functional ligand and affords selectively the hydride derivatives (eta6-arene)[eta2-Ph 2PC(R)=C(R?)O]RuH. The cleavage of the ruthenium-chlorine bond in complexes 2 is also the preliminary step involved in the coupling process of functional phosphino enolato ligands with 1-alkynes HC=CR?. The reaction results in the formation of complexes {(eta6-arene)Ru[eta3-CH=C(R?)C(R)(PPh 2)C(R?)=O]}(PF6) [R = H or Me, R? = But or Ph, R? = H, Me, Ph, p-MeC6H4, or SiMe3], the isomerization of which into complexes {(eta6-arene)Ru-[eta3-CH(PPh 2)C(R?)=C(R)C(R?)=O]}(PF6), [R? = But, R? = H, Me, Ph, or p-MeC6H4] occurs only when R = H. The isomerization consists of an intramolecular [1,3]-migration of a phosphorus-carbon bond and is catalyzed by the fluoride anion. When R? = H, a subsequent cleavage of the ruthenium-carbon bond foreshadows the formation of (eta6-C6Me6)[eta1-Ph 2-PCH2CH=CHC(=O)But]RuCl2, 11. Thus, starting from the precursor (eta6-C6Me6)[eta1-Ph 2-PCH2C(=O)But]RuCl2, the process achieves formally an insertion of ethyne into the starting functionalized phosphorus-carbon bond. The scarcely isolable complexes {(eta6-arene)Ru-[eta3-C(=CH2)C(R)(PPh 2)C(R?)=O]Ru}(PF6) [R = H or Me, R? = But or Ph] reveal an easy cleavage of the functionalized phosphorus-carbon bond. This cleavage is the preliminary step involved in the formation of metallafuran complexes {(eta6-arene)(Ph2PX)Ru[eta2-C(CH 3)=CRC(R?)=O]}(PF6) [X = Cl or F, R = H or Me, R? = But or Ph], which implies also the capture of a halide anion by phosphorus in a transient intermediate.

The halide and phosphine free complex [(sIMes)(C5H 4N-2-CO2)2RuCHPh] (7) (sIMes = 1,3-dimesitylimidazolidin-2-ylidene) bearing two bidentate 2-pyridinecarboxylato ligands was synthesized from the carbene complex [(sIMes)(PCy 3)(Cl)2RuCHPh] (4) and the silver 2-pyridine-carboxylate (8). The molecular structure of the octahedral complex 7 reveals that the two carboxylato functions are coordinated in cis geometry to the ruthenium center. Catalyst 7 exhibits activity in ring-closing metathesis (RCM) reactions after addition of a cocatalyst (HCl) in dichloromethane as well as in methanol solution.

Organometallic complexes [Ru-Colefin(sp2)-Ru(II)-Pheox 2a-2d] containing a Ru-Colefin(sp2) bond have been prepared from unsaturated chiral oxazoline derivatives and evaluated for asymmetric cyclopropanation reactions. The corresponding optically active cyclopropanes were obtained with high yields and high stereoselectivities (?99/<1 trans/cis, 99% trans ee). The enantioselectivities were found to be affected by the geminal substituent on the Ru-C(sp2) bond. In particular, Ru(II)-Prox catalyst 2c, in which there was no geminal substituent on the metal, was shown to have the highest enantioselectivities.
