Tertiary benzylamides are easily and selectively converted into aldehydes by molecular oxygen; the reaction is catalysed by N-hydroxyamides and Co(II).
## Abstract A new process for the homolytic acylation of protonated heteroaromatic bases is described; an Nβoxyl radical (PINO) generated from __N__βhydroxyphthalimide by air oxygen and Co(II) abstracts a hydrogen atom from an aldehyde. The resulting nucleophilic acyl radical adds to a heteroaromat
## Abstract The oxidation of alcohols to aldehydes and ketones by air or oxygen under mild conditions (room temperature and atmospheric pressure), catalysed by persistent and nonβpersistent nitroxyl radicals in combination with transition metal salts, appears to be the most convenient of the numero
