Ring-closing olefin metatheses (RCM) of various tethered dihexenoyl derivatives were examined under various conditions. The E:Z ratios of the resulting double bonds of the cyclic products were determined. The stereochemistry of the resulting olefins was influenced largely by the effects of the template used.

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. Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.Product Details of 37366-09-9, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 37366-09-9, in my other articles.

Electric Literature of 246047-72-3, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.246047-72-3, Name is (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, molecular formula is C46H65Cl2N2PRu. In a patent, introducing its new discovery.

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.

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.

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.
