Abstract

A Wittig reaction between 1,2-dihydro-1,2-bis(triphenylphosphoranylidene)benzocyclobutene (15) and biphenyl-2,2′-dicarbaldehyde (14) gave dibenzo[a,c]benzo[3,4]cyclobuta[1,2-f]cyclo-octene (3), whereas that between 2,2′-bis(triphenylphosphoranylidenemethyl)biphenyl (6) and benzocyclobutene-1,2-quinone (5) gave only acyclic products. Some reactions of (3) are described.
