The preparation of [U-14C] 2,4-dichlorophenol was formerly achieved by a Sandmeyer reaction with [U-14C] 2,4-dichloroaniline but this sensitive step gave unreproductive yields in our hands. We describe another route to [U-14C] 2,4-dichlorophenol by the oxidative chlorination of [U-14C] phenol. This shorter route is safer and gives satisfactory yields. The nature of the oxidizer is discussed.
