Abstract

Abstract Various ring-sized cyclic polychalcogenides fused to aromatic systems were synthesized, and the structures were sufficiently characterized. Stabilities of the rings were examined in terms of the existence of selenium atoms. Benzopolychalcogenides are unstable molecules. However, benzo [1, 2, 3, 4, 5] tetrathiaselenepins with an isopropyl group or two methoxy groups on the ring were found to be stable. Similarly, the novel ...
