Efficient photocatalytic aerobic oxidative dehydrogenation reactions of N,N-disubstituted hydroxylamines to nitrones were developed with an in situ generated photocatalyst based on commercially available 3,6-dichlorotetrazine. This process affords a wide range of nitrones in high yields under mild conditions. In addition, an oxidative (3+3) cycloaddition between an oxyallyl cation precursor and a hydroxylamine was also developed.

The 10-methylacridinium ion (MA+)-sensitized photooxidation of substituted N,N-dibenzylhydroxylamines (1) in acetonitrile occurred mainly by a superoxide ion mechanism to give N-benzylidenebenzylamine N-oxides (2) and hydrogen peroxide quantitatively. Analysis of substituent effects on the limiting quantum yield for formation of 2 showed that back electron transfer (ET) from the 10-methylacridinyl radical (MA.) to the radical cation 1+. proceeds in the Marcus 'normal region'. In addition, this back ET was found to take place in preference to one-electron reduction of O2 by MA..

Back electron transfer within geminate radical ion pairs formed by electron transfer from the title hydroxylamines to singlet 9-cyano- and 9,10-dicyano-anthracenes in acetonitrile is shown to occur in the Marcus 'inverted region' and 'normal region', resp
