“…[1,2] The first radialene, 7,8,9,10,11,12-hexamethyl [6]radialene, was prepared by Hopff and Wick in 1961. [3] Radialenes and their derivatives have been the subject of significant theoretical and experimental interest. [1,2,4,5] New approaches to the synthesis of radialenes have been developed, and these structures have become important building blocks for organic conductors and ferromagnets.…”
