When several diallyl esters were subjected to ADMET using Grubbs “first generation” catalyst only oligomerization occurred (DPs < 7), but with allyl hex-5-enoate the product had a DP of 14, and with allyl undec-10-enoate the products usually had DPs in the range 41-79. It is suggested that with the diallyl esters an intermediate is formed in which the ester carbonyl chelates onto the metal centre and that this is sufficiently stable to suppress polymerization. One possible explanation for the successful polymerization of allyl undece-10-enoate is that it is achieved indirectly via a ring-closing metathesis (RCM) to give a macrocycle that then reacts further by an entropically driven ring-opening polymerization (ED-ROMP) to give the final polymer. A cyclo-depolymerization (CDP) involving the metathesis of substituted allyl ester moieties in a polymer backbone and ED-ROMPs involving the metathesis of substituted allyl ester moieties in macrocycles catalyzed by Grubbs' "first generation" catalyst and/or the "second generation" catalyst were also successful. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

4,5-Diazafluorene ligands, (L1) and (L2), have been synthesized from the reaction of 4,5-diazafluorenone-9-hydrazone with 4-(4-fluorophenoxy) benzaldehyde and 4,5-diazafluoren-9-one with 4-(4-fluorophenoxy) benzylamine hydrochloride in dry EtOH. Ru(II) complexes of the ligands Ru(II)-L1 and Ru(II)-L2 were prepared by treating the ligands with Ru(bpy)2CI2 in dry EtOH. The metal-to-ligand ratio of the Ru(II) complexes was found to be 1:1. The ligands and complexes were characterized by elemental analysis and spectra FTIR, UV-vis, 1H NMR, MS, and fluorescence studies.

Synthetic Route of 246047-72-3. Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 246047-72-3, Name is (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium

A series of seven cyclopent-3-en-1-ylmethylamines bearing one, two, or three methyl substituents at the C2, C3, C4, or Calpha positions, including the unsubstituted parent, was accessed by ring-closing metatheses of alpha,alpha-diallylacetonitrile (or methallyl variants) and alpha,alpha-diallylacetone followed by hydride reductions or reductive amination, or by Curtius degradations of alpha,alpha-dimethyl- and 2,2,3-trimethylcyclopent-3-enylacetic acids. Oxidation of the primary amines with Pb(OAc)4 in CH2Cl2, CHCl3 or benzene in the presence of K2CO3 effected efficient intramolecular aziridinations, in all cases except the alpha-methyl analogue (16), to form the corresponding 1-azatricyclo[2.2.1.02,6]heptanes, including the novel monoterpene analogues, 1-azatricyclene and the 2-azatricyclene enantiomers. The cumulative rate increases of aziridination reactions observed by 1H NMR spectroscopy in CDCl3 resulting from the presence of one or two methyl groups on the cyclopentene double bond, in comparison to the rate of the unsubstituted parent amine (1:17.5:>280), indicate a highly electrophilic intermediate as the nitrene donor and a symmetrical aziridine-like transition state. A mechanism is outlined in which the amine displaces an acetate ligand from Pb(OAc)4 to form a lead(IV) amide intermediate RNHPb(OAc)3 proposed as the actual aziridinating species.

Treatment of Cp(PPh3)[P(OMe)3]RuC?CPh (2; Cp = eta5-C5H5) with PhN=C=S at room temperature affords the [2 + 2] cycloaddition product Cp(PPh3)[P(OMe)3]RuC=C(Ph)C-(=NPh)S (3a), containing a four-membered ring, and the neutral vinylidene phosphonate complex Cp(PPh3)[P(=O)(OMe)2]Ru=C=C(Ph)C(SH)=NPh (4a) in a 9:1 ratio. Formation of 4a results from an Arbuzov-like dealkylation reaction possibly after addition of PhN=C=S. The same reaction at 40 C affords a higher yield of 4a and Cp(PPh3)[P(OMe)3]RuC=C-(Ph)C(=S)N(R)C(=NR)S (5a; R = Ph) which results from addition of a second isothiocyanate to the four-membered ring of 3a. The reaction of 2 with PhCH2N=C=S at room temperature directly affords the six-membered-ring product 5b (R = CH2Ph). Trimerization of phenyl isothiocyanate is catalyzed by Cp(dppe)RuC=CPh (1?; dppe = Ph2PCH2CH2PPh2) in refluxing CH2Cl2. This catalytic reaction proceeds through a pathway in which the first two steps are the same as those observed in the reaction of 2a. An attempt to purify the precursor of the trimerization product gave the cocrystallization of 1? and (PhNCS)3 (8). The structures of 3a, 4a, 5b, and the cocrystallization product of 1? and 8 have been determined by single-crystal X-ray diffraction analysis.

(Chemical Equation Presented) The isolation and structural characterization of alkyne-bound Ru alkylidene complexes has been elusive. However, a sequential enyne ring-closing metathesis of a diyne moiety and metallotropic [1,3]-shift followed by a second enyne ring-closing metathesis allowed the formation of a highly stable alkyne-chelated ruthenium complex. The full characterization of this complex was realized by NMR spectroscopy and X-ray crystallography.
