Reference of 246047-72-3, An article , which mentions 246047-72-3, molecular formula is C46H65Cl2N2PRu. The compound – (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium played an important role in people’s production and life.

The present invention describes the use of soluble metal salts to reduce impurities and metathesis catalysts poisons from olefinic feedstocks to improve olefin metathesis efficiency. The soluble metal salts were added to the olefinic feedstocks to prevent peroxides and catalyst poisons from inhibiting the metathesis catalyst. The soluble metal salts remain in the olefinic feedstocks and are used without further purification in the olefin metathesis reactions. The key to this invention is the soluble metal salt compounds do not inhibit the olefin metathesis catalysts but unexpectedly increase olefin metathesis catalyst efficiency while prior art heterogeneous metal complexes sequester the olefin metathesis catalyst, preventing olefin metathesis.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 246047-72-3, help many people in the next few years., Reference of 246047-72-3

N-heterocyclic carbene (NHC) based ruthenium complexes were studied as catalysts for the transfer hydrogenation of ketones. Variations in the catalyst structure were investigated for their impact on hydrogenation and catalyst stability. Catalyst attributes included bis- or mono-NHC ligands, pendant ether groups in some cases, and arene ligands of varied bulk and donor strength. Ruthenium complexes were synthesized and fully characterized, including complexes with a monodentate NHC ligand containing a tethered ether N substituent (ImEt,CH2CH2OEtRuCl2(eta6-arene); arene = benzene (4), p-cymene (5), hexamethylbenzene (6)), a complex with a monodentate NHC ligand with solely alkyl N substituents (Im Et,PentylRuCl2(eta6-p-cymene) (8)), and a complex with a bis-NHC ligand ([RuCl(methylenebis(ImEt) 2)(eta6-p-cymene)]PF6 (7)) (Im = imidazole-derived NHC; superscripts indicate N substituents). X-ray crystal structures were obtained for 4, 5, 7, and 8. All of the ruthenium complexes were tested and found to be active transfer hydrogenation catalysts for the reduction of acetophenone to 1-phenylethanol in basic 2-propanol. Precatalyst 4, which contains a tethered ether group and benzene ligand, was found to be the most active catalyst. Variable-temperature 1H NMR studies of complexes 4-6 show that arene lability increases in the order C 6Me6 < cymene < benzene, and this lability is directly correlated with catalytic activity. The catalysis appears to be homogeneous, and a mechanism invoking arene loss is proposed. Precatalyst 4 reduced electron-deficient ketones most easily, and 4?-nitroacetophenone was reduced under base-free conditions. The highest TOF (turnover frequency) and TON (turnover number) values obtained were 3003 h-1 and 845, respectively, for ketone reduction with catalyst 4. Do you like my blog?

Pyrrolizidine, indolizidine, and pyrrolo[1,2-a]azepine substructures are present in a large number of naturally occurring azabicyclic compounds, which are currently of special interest because of their biological activities. To obtain this class of compounds, we envisioned a ring-rearrangement metathesis (RRM) process of 7-azanorbornene systems that incorporates several exocyclic olefin patterns at the nitrogen position. By using this methodology, we have synthesized a set of new 1-azabicyclo[n.3.0]alkenones, which include derivatives of pyrrolam. In all cases, only one regioisomer was obtained. Moreover, new spiro compounds with tricyclic structures have been synthesized by using a domino metathesis process that involves a ring-opening/ring-closing/ring-closing metathesis (ROM/RCM/RCM) sequence. A new synthetic strategy for nitrogen heterocycles was developed that incorporates fused-ring systems and takes advantage of a stereodefined ring-rearrangement metathesis process of substituted 7-azanorbornenes as the stereocontrolled key step. A set of new 1-azabicyclo[n.3.0]alkenones (n = 3, 4, and 5) that include new analogues of pyrrolam were prepared by using this methodology. Copyright

A stereoselective route for the total synthesis of anticancer marine natural product (+)-varitriol (1) is detailed herein. The impressive biological activity and interesting structural features of natural (+)-varitriol fuelled us to undertake the synthesis of some higher analogues (1a-j) of this molecule. The key features of the synthetic strategy include one-pot Wittig olefination followed by a highly diastereoselective oxa-Michael addition to assemble stereochemically pure tetrasubstituted THF moiety of the natural varitriol and olefin cross metathesis to couple the aromatic part with tetrasubstituted THF moiety. The total synthesis of title natural product is efficient with 21.8% overall yield for 9 linear steps from d-ribose and thus facilitates the more scaled-up practical route for the synthesis of 1 and its analogues as well. The synthetic (+)-varitriol (1) and its analogues were screened for their cytotoxicity. The present synthetic approach paves the way for preparation of numerous analogues of the title natural product for drug development.
