Triarylbismuthanes react with iodobenzene diacetate in dichloromethane under mild, neutral conditions to afford triarylbismuth diacetates, which can be isolated in good yields. The reagents can also be directly used in a one- pot copper-catalysed N-arylation of anilines to give near quantitative yields of the corresponding diarylamines, except in the case of the 2- methoxyphenylbismuth derivative. N-arylation with tris(2- methoxyphenyl)bismuth diacetate was quantitative only when the reaction was performed with the pure isolated reagent.
