Biphenylenes. Part XXVIII. Synthesis of some benzo[b]-, naphtho-[2,3-b]-, and anthra[2,3-b]-derivatives of biphenylene

Autor: Barry Edward Ayres, J. F. W. McOmie, Reda A. Kabli

Publikováno v: Journal of the Chemical Society, Perkin Transactions 1. :2267

The Friedel–Crafts acylation of biphenylene with the anhydrides of succinic, phthalic, and naphthalene-2,3-dicarb-oxylic acids has been studied. The resulting acylbiphenylenes were then converted into benzo[b]-, naphtho-[2,3-b]-, and anthra[2,3-b]-
