Abstract
A general and simple methodology for 3,6-diaryl benzocyclobutene (BCB) derivatives is reported using the Suzuki-Miyaura coupling reaction as a key step. Some of these building blocks are useful for the synthesis of a variety of BCB-based polymers.
Key words
boron - coupling - cycloadditions - polymers - palladium
