✦ Synopsis
The oxidation reaction of aniline by tertiary hydroperoxides, induced photochemically, was studied. The peculiar radicaI intermediates, nitroxides and pemxy radicak. involved in the nzaction mechanism were-detected and identified by EPR spectroscopy. The presence of these intermediates confirm that PhNO is the first product of the oxidation of aniline and the PhNH radical as its p=-.
Zntroduction
A study of the oxidation mechanism of aniline promoted by different peroxy compounds has been reported recently.1 However, among the oxidants, the hydroperoxides and the peroxides do not react spontaneously.
It is known that hydroperoxides can perform the aniline oxidation if catalytic amount of certain metal compounds are present? nevertheless, the aim of the research was to discover whether a possible oxidative process could be induced photochemically, @ a homolytic radical mechanism.3
