Direct evidence for a ruthenium(IV) oxo complex-mediated oxidation of a hydroxamic acid in the presence of phosphine oxide donors

Ruthenium(II) complexes can be used to oxidise N-Boc hydroxylamine the 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 triphenylph...

Zusammenfassung:Ruthenium(II) complexes can be used to oxidise N-Boc hydroxylamine the 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) oxocomplex as the catalytically active species.
