Reactions of Tropone Tosylhydrazone Sodium Salt with Anthracene, 1,3-Diphenylisobenzofuran, and Phenylacetylene: [2+2] and [4+2] Type Cycloaddition Reactions of Cycloheptatrienylidene or 1,2,4,6-Cycloheptatetraene

The reaction of tropone tosylhydrazone sodium salt (1) with anthracene gave a [4+2]-type adduct and the reaction of 1 with 1,3-diphenylisobenzofuran afforded endo- and exo-[4+2]-type adducts as well as a heptafulvene derivative. The reaction of 1 with phenylacetylene yielded a [2+2]-type adduct, which rearranged into 2-phenylindene upon heating. The addition reactions are thought to proceed via the
