Stereoselective total synthesis of epothilones by the metathesis approach involving C9-C10 bond formation

A stereoselective synthesis of epothilone B was achieved by the metathesis of the diene 1, by use of a new Grubbs catalyst to form the C9-C10 bond, followed by hydrogenation and deprotection of 2; TBS = tert-butyldimethylsilyl.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.COA of Formula: C46H65Cl2N2PRu, you can also check out more blogs about246047-72-3

Transition metal chemistry of phosphorus based ligands. Ruthenium(II) chemistry of bis(phosphino)amines, X2PN(R)PX2 (R=H or Ph, X=Ph; R=Ph, X2=O2C6H4)

Reactions of CpRuCl(PPh3)2 with bis(phosphino)amines, X2PN(R)PX2 (1 R=H, X=Ph; 2 R=X=Ph; 3 R=Ph, X2=O2C6H4) give neutral or cationic mononuclear complexes depending on the reaction conditions. Reaction of 1 with CpRuCl(PPh3)2 gives one neutral complex, [CpRu(Cl)(eta2-Ph2PN(H)PPh2)] (4) and two cationic complexes, [CpRu(eta2-Ph2PN(H)PPh2)(eta1-Ph 2PN(H)PPh2)]Cl (5) and [CpRu(PPh3)(eta2-Ph2PN(H)PPh2)]Cl (6), whereas the reaction of 2 with CpRuCl(PPh3)2 leads only to the isolation of cationic complex, [CpRu(PPh3)(eta2-Ph2PN(Ph)PPh2)]Cl (7). The catechol derivative 3, in a similar reaction, affords an interesting mononuclear complex [CpRu(PPh3){eta1-(C6H4O2)PN(Ph)P(O2H4C6)}2]Cl (8) containing two monodentate bis(phosphino)amine ligands. The structural elucidation of the complexes was carried out by elemental analyses, IR and NMR spectroscopic data.

Pb2Ru2O6.5 as a low-temperature cathode for bismuth oxide electrolytes

A chemical route, called direct condensation method (DCM), was developed to synthesize nanometric Pb2Ru2O6.5 as a cathode material for intermediate temperature solid oxide fuel cells. The electrolyte used was (Er2O3)0.2(Bi 2O3)0.8 (ESB). Porous lead ruthenate and ESB-lead ruthenate composite electrodes were deposited onto dense ESB pellets. X-ray diffraction, field-emission scanning electron microscopy, and energy dispersive spectroscopy analysis were used to investigate the reactivity and the morphology of the materials prepared. Electrochemical impedance spectroscopy in air at different operating temperatures was used to evaluate polarization and electrical performance of cells in symmetric configuration. Lead ruthenate-based electrodes were sintered at different temperatures to understand the role of the triple-phase boundary on the electrode polarization. An increase in the sintering temperature induced the formation of intermediate phases at the interface between ESB and the pyrochlore, thereby resulting in an increase in the polarization resistance at the electrode/electrolyte interface of the symmetric cells.

N-Heterocyclic carbene ligands bearing a naphthoquinone appendage: Synthesis and coordination chemistry

Many biochemical transformations for small molecule functionalisation depend on the temporal delivery of multiple protons and electrons. For this purpose, Nature elegantly combines transition metals with redox-active cofactors. In a biomimetic spirit, we report on the synthesis and coordination chemistry of an N-heterocyclic carbene ligand bearing a naphthoquinone moiety NHC 1. Both the silver and palladium complexes [Ag(mu-Cl)(NHC 1)]2 2 and [Pd(eta3-allyl)(NHC 1)Cl] 5 were characterized by X-ray crystallography. Cyclic voltammetry of the metal complexes suggest that redox events occur both on the naphthoquinone and on the metal for the iridium and ruthenium complexes.

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 37366-09-9, help many people in the next few years., Synthetic Route of 37366-09-9
