Light-induced and related reactions of quinones. Part I. The mechanism of formation of acetylquinol from 1,4-benzoquinone and acetaldehyde
Illumination of 1,4-benzoquinone in acetaldehyde with visible light yields acetylquinol which is shown by the use of 1,1-diphenylethylene as a scavenger to be formed via attack of acetyl radicals on the quinone. Supporting evidence is provided by reactions initiated in the dark by di-t-butyl diperoxalate.
