Abstract :
Aryl aminoacetonitriles are oxidized by NiO2–H2O or MnO2 in the presence of a wide range of NH2-containing compounds to afford aryl amidines, presumably via iminium intermediates. A ‘one-pot’ procedure for the preparation of heteroaryl amidines from N-containing heteroaryl halides through a process comprising sequential SNAr substitution and oxidation has also been developed.
