Tripyridylcyclopropene derivatives and their conversion to hexapyridylbenzene

, p. 601 - 604 (1991)
1,2,3-tris(4-pyridyl)cyclopropene carrying a 3-benzenesulfonyl group has been synthesized, and other cyclopropenes carrying pyridine and pyridinium rings. Some of these can be converted to hexa(4-pyridyl)benzene and its pyridinium analog.
Synthesis of Tripyridiniumylpropenyl Anions from Tripyridiniumylcyclopropanes and -cyclopropenes

The syntheses of three stable, isolatable tripyridiniumylpropenyl anions are described. 1,2,3-Tris(4-(N-methylpyridiniumyl))propenyl anion and 1-(benzenesulfonyl)-1,2,3-tris(4-(N-methylpyridiniumyl))propenyl anion were prepared by treating the corresponding cyclopropane with a base. 1,3-Bis(benzenesulfonyl)-1,2,3-tris(4-(N-methylpyridiniumyl))propenyl anion was prepared by nucleophilic attack of benzenesulfinate anion on 3-(benzenesulfonyl)-1,2,3-tris(4-(N-methylpyridiniumyl))cyclopropene.Reduction of this cyclopropene gave either 1-(benzenesulfonyl)-1,2,3-tris(4-(N-methylpyridiniumyl))propenyl anion or hexakis(4-(N-methylpyridiniumyl))benzene depending on the solvent used.
