General Description

2,3-Butanedione, mono(O-acetyloxime), (E)- (9CI) is a chemical compound with the molecular formula C6H10O2. It is also known as E-2,3-Butanedione O-acetyloxime. 2,3-Butanedione, mono(O-acetyloxime), (E)- (9CI) is an oxime derivative of 2,3-butanedione, a diketone found in many foods and beverages. The O-acetyloxime form of 2,3-Butanedione is used in the synthesis of various organic compounds and in laboratory research. It is also used as a flavoring agent in food products. However, exposure to 2,3-Butanedione has been linked to respiratory issues, and there are concerns about its potential health effects, particularly in occupational settings where exposure levels may be higher.

Visible Light Irradiation of Acyl Oxime Esters and Styrenes Efficiently Constructs β-Carbonyl Imides by a Scission and Four-Component Reassembly Process

Acyl radical triggered difunctionalizations of aryl olefins have been realized using oxime ester as the acyl precursor for the first time. Irradiation of fac-Ir(ppy)3 and oxime ester by visible light caused scission into three components, which recombined with olefins to yield significant β-carbonyl imides showing good functional group tolerance and high atom economy. Control experiments as well as spectroscopic and electrochemical studies revealed the efficient intermolecular reorganization of oxime ester into styrene with the aid of solvent exchange.

The effect of solvent on the α-effect: The MeCN-H2O solvent system

The increasing α-effect observed in MeCN-H2O solvent mixtures, which contrasts with the previously found bell-shaped dependence on solvent composition in the DMSO-H2O system, is attributed to the differential solvent effect on basici
