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.
Check Digit Verification of cas no
The CAS Registry Mumber 71087-81-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,0,8 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 71087-81:
(7*7)+(6*1)+(5*0)+(4*8)+(3*7)+(2*8)+(1*1)=125
125 % 10 = 5
So 71087-81-5 is a valid CAS Registry Number.

Photocatalytic C-C Bond Activation of Oxime Ester for Acyl Radical Generation and Application
Fan, Xiuwei,Lei, Tao,Chen, Bin,Tung, Chen-Ho,Wu, Li-Zhu
, p. 4153 - 4158 (2019/06/08)
A unified strategy to generate acyl radical from oxime ester via selective C-C bond activation is reported. Under visible-light irradiation, single-electron transfer from fac-Ir(ppy)3 to related oxime takes place followed by a fast β-fragment of C-C bond to yield aryl and aliphatic acyl radicals, subsequently captured by diverse Michael acceptors. More interestingly, the single-electron transfer enables coupling with energy transfer of the excited fac-Ir(ppy)3 via enone intermediate formed in situ for cyclobutane formation.
The effect of solvent on the α-effect: The MeCN-H2O solvent system
Um,Park,Buncel
, p. 1917 - 1918 (2007/10/03)
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
