Triarylbismuthane - iodobenzene diacetate: One-pot system for copper-catalysed N-arylation under neutral conditions
摘要:
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. (C) 1998 Elsevier Science Ltd. All rights reserved.
