Efficient Route to Deuterated Aromatics by the Deamination of Anilines

Burglova, Kristyna,Okorochenkov, Sergei,Hlavac, Jan

, p. 3342 - 3345 (2016)

One-step replacement of NH2 groups in ring-substituted anilines by deuterium is reported. Approaches comprising both solid-phase and solution-phase syntheses can be used on a large variety of substrates. The method uses diazotization in a mixture of water and either dichloromethane or chloroform, which serve as a source of hydrogen. This protocol can be used as a general method for fast and easy incorporation of deuterium into an aromatic system using deuterated chloroform.
