The reaction of acetyl hypofluorite in acetic acid with both cyclohexane and cyclohexene has been investigated. Analysis by GCMS and radio‐HPLC, using 18F as a tracer, revealed that, apart from typical products expected from a radical reaction, several compounds originating from carbocationic intermediates were formed. On the basis of the observed products, a single‐electrontransfer (SET) mechanism leading to an intermediate radical‐cation is proposed.
