In a document type is Article, introducing its new discovery.

Exchange of benzylidene ligand of commercially available Grubbs catalysts 1a or 1b with an appropriate soluble-polymer supported ligand leads to new boomerang type catalysts either of the Grubbs (3) or the Hoveyda type (4a or 4b). These catalysts, supported on poly(ethylene glycol) (PEG), were fully characterized by solution NMR and MALDI mass spectrometry. They were tested in ring-closing metathesis (RCM), and 1H NMR analysis provided key information concerning the recovery of the catalyst at the end of the reaction. While in the case of 3 the active ruthenium did not hook back to the ligand, catalysts 4a and 4b can be recovered and recycled. 4b owning a N-heterocyclic carbene ligand is particularly active and was used in the parallel synthesis of cyclic amino esters.

In a patent, introducing its new discovery.

Ryanodol (1) exists in nature in the form of the 1H-pyrrole-2-carboxylate ester derivative known as ryanodine, which is a potent modulator of the calcium release channel. The pentacyclic ABCDE-ring system of 1 is fabricated with eight oxy groups, three methyl groups, and one isopropyl group. All the eight tetrasubstituted stereocenters are concentrated within the 10-carbon ABDE framework. The total synthesis of this exceptionally complex molecule was achieved in 22 steps from the simple C2-symmetric tricycle 8. The synthetic route is based on installation of the seven stereogenic centers and formation of the four C-C bonds within the highly congested multicyclic format. The novel and flexible strategy developed here will enable the generation of chemical derivatives with different functional properties toward calcium release channels.

The dictyostatins are a promising class of potential anti-cancer drugs because they are powerful microtubule-stabilizing agents, but the complexity of their chemical structures is a severe impediment to their further development. On the basis of both synthetic and medicinal chemistry analyses, 16-desmethyl-25,26-dihydrodictyostatin and its C6 epimer were chosen as potentially potent yet accessible dictyostatin analogues, and three new syntheses were developed. A relatively classical synthesis involving vinyllithium addition and macrocyclization gave way to a newer and more practical approach based on esterification and ring-closing metathesis reaction. Finally, aspects of these two approaches were combined to provide a third new synthesis based on esterification and Nozaki-Hiyama-Kishi reaction. This was used to prepare the target dihydro analogues and the natural product. All of the syntheses are streamlined because of their high convergency. The work provided several new analogues of dictyostatin, including a truncated macrolactone and a C10 E-alkene, which were 400- and 50-fold less active than (-)-dictyostatin, respectively. In contrast, the targeted 16-desmethyl-25,26-dihydrodictyostatin analogues retained almost complete activity in preliminary biological assays.

Micellar media in water provide a simple and efficient environment to favor the double bond isomerization of terminal alkenes catalyzed by the cationic half-sandwich complex 1 at 95 C. The micellar medium favors both catalyst dissolution in water by means of ion-pairing with the preferred anionic surfactants as well as substrate dissolution thus favoring its conversion into products.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), Application In Synthesis of Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II).

We describe in this paper the properties of [RuII/III(bpy) 2ClL]+1/+2 and [RuII/III(bpy)2L 2]+2/+3. L = ditolyl-3-pyridylamine (dt3pya) is a redox active ligand related to triarylamines, which is very similar to 3-aminopyridine except for the reversible redox behavior. The monosubstituted complex shows a metal-to-ligand charge-transfer (MLCT) at 502 nm, and reversible waves in acetonitrile at E0(RuIII/II) = 1.07 V, E 0(L+/0) = 1.46 V (NHE). The disubstituted complex shows an MLCT at 461 nm, a photorelease of dt3pya with quantum yield of 0.11 at 473 nm, and two reversible one-electron overlapped waves at 1.39 V associated with one of the ligands (1.37 V) and RuIII/II (1.41 V). Further oxidation of the second ligand at 1.80 V forms a 2,2?-bipiridine derivative, in an irreversible reaction similar to dimerization of triphenylamine to yield tetraphenylbenzidine. In the dioxidized state, the spectroelectrochemistry of the disubstituted complex shows a ligand-to-ligand charge transfer at 1425 nm, with a transition moment of 1.25 A and an effective two-state coupling of 1200 cm-1. No charge transfer between ligands was observed when Ru was in a 2+ oxidation state. We propose that a superexchange process would be involved in ligand-metal-ligand charge transfer, when ligands and metals are engaged in complementary pi interactions, as in metal-ligand-metal complexes. Best orbital matching occurs when metallic donor fragments are combined with acceptor ligands and vice versa. In our case, RuIII bridge (an acceptor) and two dt3pya (donors, one of them being oxidized) made the complex a Robin-Day Class II system, while the RuII bridge (a donor, reduced) was not able to couple two dt3pya (also donors, one oxidized).

In an article, published in an article, once mentioned the application of 246047-72-3, Name is (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium,molecular formula is C46H65Cl2N2PRu, is a conventional compound. this article was the specific content is as follows.Quality Control of: (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium

At room temperature, NMR spectroscopy indicates that the ruthenium benzylidene complex (Cl)2(PCy3)2Ru=CHPh reacts with 1-pyrroline to yield (Cl)2(PCy3)(1-pyrroline)Ru=CHPh. Heating a solution of (Cl)2(PCy3)2Ru=CHPh with excess 1-pyrroline to 90C results in ring-opening oligomerization of the cyclic imine. The combination of ruthenium carbene complexes (Cl)2(PCy3)2Ru=CHPh and (Cl)2(PCy3)(H2IMes)Ru=CHPh (H2IMes = 1,3-dimesityl-4,5-dihydroimidazolylidene) with acyclic imines of the type (R)N=CH(R?) results in metathesis reactions when the imine possesses a C-H bond alpha to the imine carbon. Imines that lack C-H bonds alpha to the imine carbon do not react with (Cl)2(PCy3)2Ru=CHPh. The primary products from the reactions of (Cl)2(PCy3)2Ru=CHPh and (Cl)2(PCy3)(H2IMes)Ru=CHPh with acyclic imines are olefins and new Fischer carbene complexes of the type (Cl)2(L)(L?)Ru=CH{N(H)R} (L = L? = PCy3; L = PCy3 L? = H2IMes). The ruthenium complex (Cl)2(PCy3)2Ru=CH{N(H)Pr} has been isolated from the reaction of (Cl)2(PCy3)2 Ru=CHPh with (Pr)N=CH(i-Pr) and has been fully characterized. A possible pathway for the reactions of (Cl)2(PCy3)2Ru=CHPh and (Cl)2(PCy3)(H2IMes)Ru=CHPh with acyclic imines that involves imine to enamine tautomerism followed by C=C bond metathesis reactions is discussed. The failure of the ruthenium benzylidene complexes (Cl)2(PCy3)2Ru=CHPh and (Cl)2- (PCy3)(H2IMes)Ru=CHPh to react with the C=N bonds of a cyclic imines in combination with observed reactivity between Ru(Cl)2(PPh3)3 and 1-pyrroline indicates that the oligomerization of 1-pyrroline with (Cl)2(PCy3)2Ru=CHPh likely proceeds via a Lewis acid catalyzed mechanism.
