Straightforward coordination-driven supramolecular chemistry preparation of a discrete solid-state luminescent Cu-4 polymetallic compact assembly based on conformationally flexible building blocks

The ditopic nitrile-capped 1,4-phenylenediacetonitrile linker L-3 featuring partial conformational flexibility was reacted with a flexible pre-assembled Cu(I) dimer stabilized by the bis(diphenyl-phosphino)methane dppm ligand along adaptive coordination-driven supramolecular assembling processes. It resulted in the selective and unexpected formation of a compact tetrametallic assembly associating two bimetallic building blocks with three ditopic linkers. The solid-state photophysical studies of this original Cu(I)-based assembly were analysed and showed its attractive luminescence properties.

ANALOGS OF THE MARINE IMMUNOSUPPRESSANT MICROCOLIN-A – PREPARATION AND BIOLOGICAL-ACTIVITY

A series of analogs of the immunosuppressive lipopeptide microcolin A has been prepared and evaluated for in vitro activity in the human and murine two-way mixed lymphocyte reaction. The compounds tested were obtained by semisynthetic modification and chemical degradation of the natural product. The relative potencies of these analogs suggest that the hydroxyproline and 5-methyl-3-pyrrolin-2-one portion of the molecule are important for immunosuppressive activity and that other structural elements may play an ancillary role. Methanolysis of microcolin A also led to a novel immunosuppressive lactone analog.

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. you can also check out more blogs about 112275-50-0. Recommanded Product: 112275-50-0.

The Hallmarks of Copper Single Atom Catalysts in Direct Alcohol Fuel Cells and Electrochemical CO2 Fixation

Single-atom catalysts (SACs) are highly enviable to exploit the utmost utilization of metallic catalysts; their efficiency by utilizing nearly all atoms to often exhibit high catalytic performances. To architect the isolated single atom on an ideal solid support with strong coordination has remained a crucial trial. Herein, graphene functionalized with nitrile groups (cyanographene) as an ideal support to immobilize isolated copper atoms G(CN)-Cu with strong coordination is reported. The precisely designed mixed-valence single atom copper (G(CN)-Cu) catalysts deliver exceptional conversions for electrochemical methanol oxidation (MOR) and CO2 reduction (CO2RR) targeting a closed carbon cycle. An onset of MOR and CO2RR are obtained to be approximate to 0.4 V and approximate to-0.7 versus Ag/AgCl, respectively, with single active sites located in an unsaturated coordination environment, it being the most active Cu sites for both studied reactions. Moreover, G(CN)-Cu exhibited significantly lower resistivity and higher current density toward MOR and CO2RR than observed for reference catalysts.

Theoretical Study of the Mechanism of Palladium(0)-Catalyzed Intramolecular [2+2+2] Cycloaddition of Ester-Substituted Alkynes

The mechanisms of the palladium(0)-catalyzed cross [2+2+2] cycloaddition of a diyne diester with dimethyl acetylenedicarboxylate and of the [2+2+2] cyclization of a triyne diester were investigated using density functional theory calculations. After evaluating the kinetic and thermodynamic profiles of each reaction, the roles of the ester substituents on the alkyne substrates and of the triphenylphosphine ligand are discussed based on the obtained results. Moreover, the previously unreported cross [2+2+2] cycloaddition of the diyne diester with nitriles was also investigated, in order to evaluate its feasibility under the relevant experimental conditions.

Racemic (2)-pyrrolin-4-ones (i.e. 4-pyrrolones), easily available in two steps from N-protected -amino acids, undergo organocatalysed asymmetric Mannich-type addition to isatin-derived ketimines to furnish the non-racemic oxindole-(2)-pyrrolin-4-one adducts, stereoselectively (up to 96% ee, dr15:1). The oxindole-pyrrolone products feature vicinal tetrasubstituted carbon stereocenters. The developed protocol has a broad substrate scope and tolerates diverse substituents at position C-5 in 4-pyrrolones and at positions N-1 and C-5/7 in isatin imines.
