胺类化合物与分子氧形成接触电荷转移复合物(CCT,Contact Charge Transfer Complex),本文研究了卤代烷存在下芳香叔胺与O_2 CCT的光化学反应,分析结果表明反应产物为胺正离子自由基盐,以N,N-二甲基对甲苯胺为例,产物为胺正离子自由基盐具有一定的氧化性,可将肾上腺素氧化成肾上腺素红,本文对卤代烷存在下胺与O_2 CCT光化学反应机理作了初步阐述,并讨论了肾上腺素氧化反应的机理。
Amines and molecular oxygen form contact charge transfer complex (CCT). In this paper, the photochemical reaction of aromatic tertiary amines with O 2 CCT in the presence of alkyl halides was studied. The results showed that the reaction products were amine cation free radical salts, Taking N, N-dimethyl-p-toluidine as an example, the product is an amine cation radical with a certain degree of oxidation and can oxidize epinephrine to adrenaline red. In this paper, the photochemical reaction mechanism between amine and O 2 CCT in the presence of alkyl halide Made a preliminary exposition, and discussed the mechanism of epinephrine oxidation reaction.
