Abstract

Mono- and dibenzoannelated [2.2]paracyclophanes 12 and 1 were synthesized by palladium-catalyzed twoand four-fold alkenylation of vicinal di- and tetrabromides 5 and 6, respectively, and subsequent electrocyclization/ dehydrogenation of the resulting (E,Z,E)-trienes. Further extensions of the annelated ring systems, leading to the tetrahydronaphthalene derivative 15, the bis-terphenylene ...
