Selective N-Arylation of Aminobenzanilides under Mild Conditions Using Triarylbismuthanes

“…Because anilines are widely available as precursors to this class of compounds, a number of methods have been developed for the arylation of aromatic amino groups. Classical methods for this transformation, typified by the Ullmann−Goldberg condensation, often require high temperatures, long reaction times, or other harsh or stringent conditions incompatible with many functional groups. Accordingly, novel protocols have been developed to address these limitations.…”

Fischer indolisation and related compounds. Part 21. Direction on the cyclisation in the Fischer indolisation of ethyl pyruvate 2-(p- or m-substituted phenyl)phenylhydrazones

“…(c) Ethyl (16). A solution of NaNO, (2.963 g) in water (12 ml) was added to a stirred solution of 3,5-dimethoxyaniline2' (5.455 g) in concentrated HCl (7.1 ml) and water (28 ml) at &-4 "C to give a diazonium salt solution.…”
