Cross-coupling study of iodo/chloropyridines and 2-chloroquinoline with atom-economic triarylbismuth reagents under Pd-catalysis
摘要:
This study describes the palladium-catalyzed couplings of iodopyridines, chloropyridines, and chloroquinoline with atom-economic BiAr3 reagents in sub-stoichiometric loadings. Mono-arylations of iodo and chloropyridines produced arylpyridines in high yields. The couplings addressed with dihalopyridines have afforded chemo- and regio-selective coupling products. Arylations of 2-chloroquinoline with different triarylbismuth reagents demonstrated fruitful coupling reactivity under the established conditions. This sumptuous study demonstrates the remarkable cross-coupling reactivity of iodo/chloropyridines and chloroquinoline with triarylbismuth reagents. (C) 2014 Elsevier Ltd. All rights reserved.
