Mechanistic pathways for the cyclization of 1,5-alkynylacetal with N2CHTMS in the presence of Cp- and Cp*RuCl(cod) to afford (Z)- and (E)(trimethylsilyl)vinyl spiroacetals were calculated Calculations show three conformers in equilibrium for the initially formed ruthenium carbenes. Differences in the stabilities and reactivities of the conformers, depending on the use of a Cp or Cp* ruthenium catalyst, are responsible for the favorable active reaction pathways in each case, even though the geometry of the resulting product is the same regardless of the catalyst used. Kinetic Monte Carlo (KMC) simulations with rate coefficients, including tunneling probabilities for the hydride transfer step, were used to model the evolution of reactants, intermediates, and products for all calculated pathways. One path is almost exclusively active for each catalyst. Finally, the energetic span model of Kozuch and Shaik was used to calculate the energetic span (δE), the TOF-determining transition state (TDTS), the TOF-determining intermediate (TDI), and the TOF value for each of the feasible mechanistic pathways.

Quality Control of Chloro(1,5-cyclooctadiene)(pentamethylcyclopentadienyl)ruthenium. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Chloro(1,5-cyclooctadiene)(pentamethylcyclopentadienyl)ruthenium, is researched, Molecular C18H28ClRu, CAS is 92390-26-6, about Construction of isochromenes via a ruthenium-catalyzed reaction of oxabenzonorbornenes with propargylic alcohols. Author is Villeneuve, Karine; Tam, William.

Scope and mechanism of ruthenium-catalyzed cyclization of a propargylic alcs. with 7-oxanorbornadienes in methanol, yielding substituted isochromenes, are explored. Reaction of 2,3-benzo-7-oxanorbornadienes, 1-R3-2,3-(R1CHCHR2CHR2CHR1)-1,4-Y-C6H2 (2a R1 = R2 = R3 = H, Y = O; 2b R1 = OMe, R2 = R3 = H, Y = O; 2c R2 = OMe, R1 = R3 = H, Y = O; 2f R1 = OAc, R2 = H3 = H, Y = CH2; 2g R3 = Me, R1 = R2 = H, Y = O; 2h R3 = CO2Me, R1 = R2 = H, Y = O; 2i R3 = COMe, R1 = R2 = H, Y = O), 5,6-bis(methoxymethyl)-7-oxanorbornene (2d) and di-Me 7-oxanorbornadiene-2,3-dicarboxylate (2e) with propargyl alcs. EWG-CCHR4(OH) (4a-i; R4 = Me, Cy, tBu, CH2tBu, CH2Ph, Ph, EWG = CO2Et, CO2tBu), catalyzed by Cp*Ru(COD)Cl in MeOH, gave 1-[R4COCH2C(EWG):CH]-4-R3-5,8-R12-6,7-R22-1H-isochromenes (7a-q; same R, EWG). The proposed mechanism herein discussed for the formation of the product involves six major steps, the first four being oxidative cyclization, β-hydride elimination, hydroruthenation, followed by [2+2] cycloreversion. The ruthenium carbene formed at this stage undergoes a [1,3]-alkoxide shift that provides the observed product after reductive elimination. This process, believed to occur via a cationic ruthenium species, is in competition with two other pathways, ruthenium-catalyzed [2+2] cycloaddition and cyclopropanation. Although both [Cp*Ru(CH3CN)3]PF6 and Cp*Ru(COD)Cl are effective catalysts, the latter gives better yield and product ratio. The reaction was also found to proceed with high regioselectivity and product selectivity when unsym. alkenes bearing a coordinating functional group at the bridge junction were used.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Interligand Interactions Dictate the Regioselectivity of trans-Hydrometalations and Related Reactions Catalyzed by [Cp*RuCl]. Hydrogen Bonding to a Chloride Ligand as a Steering Principle in Catalysis, published in 2015-04-29, which mentions a compound: 92390-26-6, Name is Chloro(1,5-cyclooctadiene)(pentamethylcyclopentadienyl)ruthenium, Molecular C18H28ClRu, Application In Synthesis of Chloro(1,5-cyclooctadiene)(pentamethylcyclopentadienyl)ruthenium.

Reactions of internal alkynes with R3M-H (M = Si, Ge, Sn) follow an unconventional trans-addition mode in the presence of [Cp*Ru(MeCN)3]PF6 (1) as the catalyst; however, the regioselectivity is often poor with unsym. substrates. This problem can be solved upon switching to a catalyst comprising a [Ru-Cl] bond, provided that the acetylene derivative carries a protic functional group. The R3M unit is then delivered with high selectivity to the alkyne-C atom proximal to this steering substituent. This directing effect originates from the ability of the polarized [Ru-Cl] bond to engage in hydrogen bonding with the protic substituent, which helps upload, activate, and lock the alkyne within the coordination sphere. An addnl. interligand contact of the chloride with the -MR3 center positions the incoming reagent in a matching orientation that translates into high regioselectivity. The proposed secondary interactions within the loaded catalyst are in line with a host of preparative and spectral data and with the structures of the novel ruthenium π-complexes in the solid state. Also, the first x-ray structure of a [Ru(σ-stannane)] complex is presented, which indeed features peripheral Ru-Cl···MR3 contacts; this adduct also corroborates that alkyne trans-addition chem. likely involves σ-complexes as reactive intermediates. Finally, it is discussed that interligand cooperativity might constitute a more general principle that extends to mechanistically distinct transformations. The presented data therefore make an interesting case for organometallic chem. that provides inherently better results when applied to substrates containing unprotected rather than protected -OH, -NHR, or -COOH groups.
