Rhodium nanoparticles were assembled on carbon nanotubes, and the resulting nanohybrid was studied in the aerobic oxidation of hydroxylamines to nitrones. Two catalytic systems were developed (i.e., direct or co-catalytic) and both operated to provide high yields of the products, under mild conditions, but with their own specificity as regards the kinetics and regioselectivity of the transformation. In addition, the in situ cycloaddition of the produced nitrones with different alkynes was investigated.

Triphenylbismuth carbonate was shown to act as a mild, selective and efficient reagent for the oxidation of hydroxylamines. The developed reaction conditions were shown to be compatible with the in situ trapping of the produced nitrones by a strained alkyne, via a [3 + 2] cycloaddition reaction.

Strain-promoted cycloadditions of diazo compounds with dibenzocyclooctyne proceed with second-order rate constants of >10 L mol-1s -1 at 25 °C. These reactions display rate constants that are comparable or greater than those of the analogous reactions of nitrones or azides with cyclooctynes.

Strain-promoted cycloadditions of nitrones with cyclooctynes (k2 = 1.5 M-1 s-1 at 25 °C) are up to 25 times more rapid than comparable reactions of azides. The Royal Society of Chemistry 2010.
