Biomimetic epoxide-opening cascades of polyepoxides enable the efficient and rapid construction of polyether frameworks. Herein, we show that the epoxide-opening cascade cyclization that affords tetrahydrofuran products in acidic aqueous media produces tetrahydropyran (THP) in neutral water. THP formation proceeded by simply heating polyepoxides in neutral water and followed a different cyclization mode from those observed so far. The novel cascade cyclization in H2O was applied to the synthesis of a new nerolidol-type sesquiterpenoid, resulting in revision of the proposed structure and determination of the absolute configuration.

Reference of 114615-82-6, An article , which mentions 114615-82-6, molecular formula is C12H28NO4Ru. The compound – Tetrapropylammonium perruthenate played an important role in people’s production and life.

The reaction of diarylacetylenes with CoCl(PPh3)3 and sodium cyclopentadienylide or sodium carbomethoxycyclopentadienylide gave (eta4-tetra-arylcyclobutadiene)(eta5-cyclopentadienyl)cobalt and (eta4-tetra-arylcyclobutadiene)(eta5-carbomethoxycyclopentadienyl)cobalt, respectively, where aryl = para-XC6H4 (X = CF3, F, MeO). The reaction was unsuccessful for the synthesis of (eta4-tetra(para-methoxyphenyl)cyclobutadiene)(eta5-cyclopentadienyl)cobalt, which was synthesised instead from dicarbonyl(eta5-cyclopentadienyl)cobalt. In all of the examples starting with CoCl(PPh3)3 an intermediate (eta5-cyclopentadienyl)- or (eta5-carbomethoxycyclopentadienyl)(triphenylphosphine)-2,3,4,5-tetraarylcobaltacyclopentadiene complex was isolated, and two examples were characterised by X-ray crystallography. Heating the (eta5-cyclopentadienyl)- or (eta5-carbomethoxycyclopentadienyl)(triphenylphosphine)-2,3,4,5-tetraarylcobaltacyclopentadiene complexes resulted in clean conversion to the corresponding metallocenes. The influence of the para-aryl substituents on the 1H NMR of the cyclopentadienyl moiety is tabulated, together with the influence of a range of R substituents in (eta4-tetraphenylcyclobutadiene)(eta5-RC5H4)cobalt (R = CO2Me, CH2OH, Me, CHO, CCH, CO2H, CN, CONHR1, 2-oxazolinyl, NH2, NHAc, HgCl, Br, I, SiMe3, SnMe3, Ph).

A modified glassy carbon electrode, prepared by potentiostatic electrodeposition of platinum-ruthenium nanoparticles (Pt-RuNPs) onto a multi-walled carbon nanotube (MWCNT) layer, offers dramatic improvements in the stability and sensitivity of voltammetric responses toward methyldopa (m-dopa) compared to glassy carbon electrodes individually coated with MWCNT or Pt-RuNPs. The surface morphology and nature of the hybrid film (Pt-RuNPs/MWCNT) deposited on glassy carbon electrodes was characterized by scanning electron microscopy (SEM), cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) techniques. A remarkable enhancement in the microscopic area of the electrode together with the catalytic role of the composite modifier resulted in a considerable increase in the peak current (110 times) and a negative shift (-200 mV) in the oxidation peak potential of m-dopa. The mechanism of the electrocatalytic process on the surface of the modified electrode was analyzed via cyclic voltammograms at various potential sweep rates and pHs of the buffer solutions. Differential pulse voltammetry was applied and shown to provide a very sensitive analytical method for the determination of sub-micromolar amounts of m-dopa, for which a linear dynamic range of 0.05-40 muM and a detection limit of 10 nM was obtained. The modified electrode was successfully used for accurate determination of trace amounts of m-dopa in pharmaceutical and clinical preparations.

Reactions of [RuH(CO)Cl(PPh3)3] with Na2S2C2(CN)2 (referred hereafter as Na2mnt) lead to the formation of [RuH(CO)(PPh3)2{S2C2(CN) 2}]- which, upon treatment with [RuCp(EPh3)2Cl], yields neutral complexes with the general formulation [RuH(CO)(EPh3)2{S2C2(CN) 2}RuCp(EPh3)] (E = P, As, Sb). These complexes have been characterized by various physico-chemical techniques (elemental analyses, IR, 1H, 13C and 31P NMR and electronic spectra).

A document type is Article, introducing its new discovery.

We described the highly efficient synthesis of cis-hydrindenols from 2-allylbicyclo[2.2.2]octenol derivatives using the Diels-Alder adducts of masked o-benzoquinones (MOBs) with suitable dienophiles, as precursors for ring-rearrangement metathesis (RRM). These facile, versatile, and operationally simple transformation strategies produced cis-hydrindenol products with four stereo-centers and a tertiary hydroxyl functional group.
