A variety of tertiary, secondary and primary organonitrogen compounds have been efficiently and selectivity oxidized to their corresponding N-oxides, nitrones, and nitro compounds with molecular oxygen using methyltrioxorhenium as catalyst.
## Methoxy-substituted benzenes 1 are oxidized with aqueous hydrogen peroxide catalyzed by methyltrioxorhenium( VII) in acetic acid to yield the p-benzoquinones 3 in moderate yields. An intermediary diperoxo rhenium(W) complex rather than peracetic acid is the dominating oxidizing species, since o
