Dual photoredox/palladium-catalyzed C-H acylation of 2-arylpyridines with oxime esters

An unprecedented dual photoredox/palladium-catalyzed iminyl-radical-mediated C-C bond cleavage and directed ortho C-H acylation of 2-arylpyridines by using oxime esters is described. Oxime esters can serve as efficient acyl sources through formation of the corresponding acyl radicals by photoredox-catalyzed iminyl-radical-mediated C-C bond cleavage. This redox-neutral protocol features excellent regioselectivity, a broad substrate scope, and good functional-group tolerance with respect to both components, giving a broad range of aryl ketones with generally good yields.

Dicobaloxime/organodicobaloximes bridged by different axial groups: Synthesis, characterization, spectroscopy, and catalysis

In this study, the various ligands axially coordinated to two cobalt center bound to the N4-oxime core in 12 new dicobaloxime/organodicobaloxime (1-12) complexes have been synthesized and characterized by NMR (1H and 13C), UV-Visible, FT-IR, LC-MS, molar conductivity analysis, melting point, and magnetic susceptibility experiments with elemental analysis. These spectroscopic results indicate that the formation of new dicobaloxime/organodicobaloxime (1-12) complexes. The (C=N-OH) peaks disappeared in the 1H-NMR spectrum of dicobaloxime/organodicobaloxime (1-12) complexes, while new peaks were observed at range 20.18-18.33 ppm, indicating that the groups of ligands have been transformed to intramolecular H-bridge (O-H?O). The dicobaloxime (1-6) species give a better cyclic voltammogram as compared to its organodicobaloxime derivatives (7-12) due to cyclic voltammograms of the organodicobaloximes (7-12) were poor. This is possibly due to the enhanced σ donation by R groups in the organocobaloximes which are substantially stabilized. The organodicobaloxime (10) showed much better catalytic activity compared to the other cobaoxime complexes. Graphical Abstract: The different dicobaloxime (1-6) and organodicobaloximes (7-12) have been synthesized for the first time. Their redox properties were investigated using cyclic voltammetric (CV) techniques in a DMSO solution. These dicobaloximes/organodicobaloximes have been used as homogeneous catalyst for synthesis of cyclic carbonates presence of DMAP as co-catalyst.[Figure not available: see fulltext.]

Synthesis of the Multinuclear Cobaloxime Complexes via Click Chemistry as Catalysts for the Formation of Cyclic Carbonates from Carbon Dioxide and Epoxides

In this study, the structurally similar multinuclear cobaloxime complexes based on dioxime ligands were synthesized and characterized as trinuclear complexes with respect to varied axial groups. The multinuclear cobaloxime complexes were characterized by 1H, 13C-NMR, FT-IR, UV-Vis, LC-MS spectra, melting point and magnetic susceptibility measurements. These multinuclear cobaloxime complexes have been successfully applied to the synthesis of cyclic carbonates from CO2 and epoxides under optimized conditions and without using any solvent. All multinuclear cobaloxime complexes obtained by click chemistry are good catalysts for the cycloaddition of CO2 to different epoxides in the presence of pyridine as a co-catalyst. Additionally, the effects of epoxides, bases, temperature, pressure, and time on the yield of cyclic carbonates were investigated.

Reaction of Z isomers of alkylaromatic 1,2-hydroxylamino oximes with 1,2-diketones

The reactions of Z isomers of alkylaromatic 1,2-hydroxylamino oximes containing the hydroxylamino group at the primary or secondary carbon atom with diacetyl afford 6-acetyl-5,6-dihydro-4H-1,2,5-oxadiazines. The reactions of these compounds with alkylaromatic 1,2-diketones produce N-substituted α-aroylnitrones or 6-aroyl-5,6-dihydro-4H-1,2,5-oxadiazines or, alternatively, their tautomeric mixtures.
