    Description / Table of Contents: Reaction of Naphthalene, Anthracene and Phenanthrene with DichlorocarbeneNaphthalene (1), anthracene (4) and phenanthrene (8) are allowed to react with CCl2 by Makosza's method. 1 and 4 yield the chlorocycloheptatrienes 2a - c or 5c, and 3 or 6. Phenanthrene (8) gives the norcaradiene 9a which is cleaved to 10 or 11 under drastic conditions. On treatment with butyllithium 8 undergoes substitution to give 9b - d only.
