Pd-catalyzed threefold arylations of mono, di and tetra-bromoquinones using triarylbismuth reagents?

RSC Advances Pub Date: 2012-10-11 DOI: 10.1039/C2RA22058J

Abstract

The palladium-catalyzed efficient cross-couplings of mono-, di- and tetra- bromo-1,4-quinones with triarylbismuth reagents were developed, involving threefold arylation. This first time study which is demonstrated with a wide variety of substrates possesses high synthetic utility and furnished a plethora of arylated 1,4-quinones in a one-pot operation.
