Abstract

Ruthenium(II) complexes can be used to oxidise N-Boc hydroxylamine in the presence of tert-butylhydroperoxide to the corresponding nitroso dienophile, which is trapped using cyclohexa-1,3-diene as the hetero-Diels–Alder adduct; direct evidence has been obtained for the intervention of a triphenylphosphine oxide-stabilised ruthenium(IV) oxo-complex as the catalytically active species.
