The synthesis of Benzo[4,5]cyclohepta[1,2,3-de]naphthalene

Abstract

Muller et al have recently reported a synthesis of benzo[4,5] cyclohepta[1,2,3-de]naphthalene by a dehydrogenation reaction. Some investigations into alternative routes to this compound are now reported. One of these succeeded in giving a compound identical with that described by the previous workers.
