Electrochemical synthesis of 1,2-diketones from alkynes under transition-metal-catalyst-free conditions

We report an electrochemical protocol for the direct oxidation of internal alkynes in air to provide 1,2-diketones. A variety of functional groups and heterocycle-containing substrates can be tolerated well under mild conditions.

Synthesis of a new class of cationic Pd(II) complexes with 1,2,3-triazol-5-ylidene ligand and their catalytic application in the conversion of internal alkynes to 1,2-diketones

A new class of cationic Pd(II) complexes of the type [Pd(Tz)(Cl)(bipy)]+Cl? and [Pd (Tz)(Cl)(phen)]+Cl? (Tz = 1,4-diaryl-3-methyl-1,2,3-triazol-5-ylidene, bipy = 2,2′-bipyridine and phen = 1,10-phenanthroline) with various wing tip groups were synthesized from the corresponding 1,2,3-triazolium iodide via the corresponding chloro bridged dinuclear complexes [(Tz)(Cl)Pd(μ-Cl)2Pd(Cl)(Tz)]. The synthesized cationic complexes were screened for their catalytic activity of hydration of alkynes and found to be excellent towards the selective conversion of internal alkynes to the corresponding 1,2-diketones in good yields. A plausible mechanism was proposed for this conversion.

New DMSO-Based Reagents in Oxidation of Double and Triple Bonds and Synthesis of 1,2-Diketones

Preparative possibilities of oxidation of arylethenes and arylethynes using new reagents, iodine or palladium compounds in dimethylsulfoxide, in syntheses of 1,2-diketones are considered.The system PdCl2-Me2SO is shown to possess lower activity as compared to I2-Me2SO in oxidation of the double bonds, higher selectivity in oxidation of the triple bonds of diarylethynes and phenylpropyne, but more sensitive to steric effects of the substrate.

CONVENIENT PREPARATION OF UNSYMMETRICALLY SUBSTITUTED BENZILS BY PERMANGANATE OXIDATION OF β-OXO PHOSPHORUS YLIDES

Oxidative cleavage of a range of ylides 4 with R1 and/or R2 being aromatic groups, using KMnO4 in a two-phase system, affords unsymmetrical benzils and 1-arylpropane-1,2-diones 5 in moderate to good yield, and the ylide formation and oxidation can be combined in a convenient one-pot method.Key words: Phosphorus ylides, oxidation, 1,2-diketones, benzils, permanganate, oxoalkylidenetriphenylphosphoranes.

Aroyl Anion Trapping Reactions. A Preliminary Study of Direct Nucleophilic Aroylation by Means of Low Temperature, in situ (CH3)nC6H5 nLi/CO Systems.

Results of studies of the in situ nucleophilic aroylation of PhCO2Me, Me3CCO2Me and Ph2CO by several low temperature ArLi/CO systems (Ar = C6H5, p-CH3C6H4, o-CH3C6H4, 2,6-(CH3)2C6H3 and 2,4,6-(CH3)3C6H2) are reported.The experiments with C6H5Li were unsuccessfull and the best results were obtained with 2,6-(CH3)2-C6H3Li.
