Reaction of nitroalkanes with Grignardreagents, in the presence of anhydrous CeCl3 in tetrahydrofuran at –78 °C, affords N,N-disubstituted hydroxylamines in fair to good yields, depending on the nature of the reagent used.
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
