Synthesis of Functionalized 2-Arylthiophenes with Triarylbismuths as Atom-Efficient Multicoupling Organometallic Nucleophiles under Palladium Catalysis

摘要

Atom-efficient cross-coupling reactions of functionalized 2-bromo- and 2-iodothiophenes have been demonstrated using triarylbismuths as atom-efficient multicoupling organometallic nucleophiles under palladium-catalyzed conditions. These couplings with various functionalized triarylbismuths proceeded smoothly to afford the corresponding functionalized 2-arylthiophenes in high yields.
