Usage

General Description

(2E)-butane-2,3-dione O-acetyloxime, also known as 2,3-butanedione oxime, is a chemical compound commonly used in the rubber industry as a vulcanization accelerator for natural and synthetic rubber. It is also used as a flavoring agent in food products and as a fragrance component in perfumes and other cosmetic products. The compound is a yellow to orange solid with a melting point of 66-68°C and is soluble in water and organic solvents. It has been found to have potential toxic and irritant effects on the skin, eyes, and respiratory system, and has been linked to respiratory diseases such as bronchiolitis obliterans, also known as "popcorn lung", in workers exposed to high levels of the compound. Thus, proper handling and safety measures should be taken when working with (2E)-butane-2,3-dione O-acetyloxime.

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.

Reactivity studies of carbon, phosphorus and sulfur-based acyl sites with tertiary oximes in gemini surfactants

Kinetic studies of the reactions of tertiary oximes (monoisonitroso acetone; MINA and butane 2,3 dione monooxime; BDMO) with some carboxylate (p-nitrophenyl acetate and p-nitrophenyl benzoate), phosphate (p-nitrophenyl diphenyl phosphate and bis (2,4-dini

Comparative nucleophilic reactivities in carboxylate, phosphinate, and thiophosphate esters cleavage

Nucleophilic substitution reaction of p-nitrophenyl acetate (PNPA),p-nitrophenyldiphenyl phosphinate, and pesticide parathion with different a-nucleophiles [I] have been studied at 27°C in different pH in the presence of a novel cationic surfactant. [image omitted] The kinetic study was performed spectrophotometrically under pseudo-first order conditions with the α-nucleophile in excess. The pKa of nucleophiles have also been determined by kinetic method. In the presence of surfactant, the rate constant increased with increasing surfactant concentration up to a limiting value. This behavior has been analyzed in quantitative terms on the basis of pseudo-phase model of micellar catalysis. Finally the nucleophilic reactivity of hydroxamate ions has been compared with other α-nucleophiles, like oxime, hydroxybenzotriazole, and 2-iodosobenzoic acid (IBA). The order of cleavage of electrophilic centers, that is, C=O, P=O, and P=S have also been discussed. Copyright
