## Abstract A new process for the homolytic acylation of protonated heteroaromatic bases is described; an N‐oxyl radical (PINO) generated from __N__‐hydroxyphthalimide by air oxygen and Co(II) abstracts a hydrogen atom from an aldehyde. The resulting nucleophilic acyl radical adds to a heteroaromat

Tertiary benzylamides are easily and selectively converted into aldehydes by molecular oxygen; the reaction is catalysed by N-hydroxyamides and Co(II).
