description

2H-Benzo[b]thiete 1 reacts with cyclopentadiene 3 in consecutive [8π + 2π]cycloadditions yielding the condensed heterocycles 6–8. Tetracyclone 9 on the other hand gives only the monoadduct 10. An [8π + 8π]cycloaddition can be observed for 1 and diphenylisobenzofuran 11. The related π system 13 shows again consecutive [477π + 27π]processes (1 + 13 ← 14, 15).
