Abstract
Palladium-catalysed cross-coupling of 2,3-dibromobenzo[b]thiophene with phenylboronic acids bearing two ortho substi-tuents have been developed and used for the synthesis of sterically hindered 2,3-diarylbenzo[b]thiophenes.
Key words
Suzuki cross-coupling reaction - palladium - steric hindrance - regioselectivity - 2,3-diarylbenzo[b]thiophenes
