| Abstract: | Reactions of diarylmethyl anions whose conjugate acids are more acidic than diphenylmethane with tetrachlorocyclopropene are found to afford hexaaryl-3]radialenes in modest to good yields, thus leading to the first synthesis of hexaphenyl3]radialene itself too; X-ray crystalographic analysis of hexakis(p-cyanophenyl)3]radialene reveals a double three-bladed conformation. |
