Dibenzo[a,c]cyclooctatetraenes were selectively generated in good yields from the palladium-catalyzed [4+4] cyclic homocoupling of borylvinyl iodobenzene derivatives, which were prepared via the selective Suzuki-Miyaura cross-coupling of the gem-diboryl reagents with iodo compounds.
We are recently working on the preparation and synthetic applications of polyhalo and polyboryl compounds, expecting cooperative effect among those polyfunctional groups. This is a good example of synthetic applications of our polyhalo and polyboryl compounds.
