Nitrooxylation
WebbSulfhydration, like nitrosylation, occurs on reactive cysteine residues. In several instances, sulfhydration occurs on the same cysteine residue as nitrosylation. The two … Webb1 jan. 1984 · C–H Nitrooxylation at benzylic positions has been achieved by employing the N-hydroxyphthalimide (NHPI) catalyst/cerium(IV) ammonium nitrate (CAN) reagent system.The nitrooxy groups were demonstrated to function as tentative hydroxy protecting groups, as well as excellent leaving groups for N- and C-substitution reactions.
