    Description / Table of Contents: Light-induced [2 + 2] Cycloaddition Reactions of Thiones with Cyclic AlkenesUnder n→π* excitation using sodium light, xanthione (1) combines with acenaphthylene, indene or N-phenyl maleoylimide in good yields with formation of the spirothietane drivatives 3, 7, or 8, respectively. The analogous photoreactions (λ ≍ 400 nm) of the 2-thioparabanate 4 in the presence of indene, benzo[b]furan or N-phenyl maleoylimide proceed with formation of the spirothietanes 6a, b, or 9, respectively. The thietane structures are consistent with spectroscopic data.
    Notes: Bei n→π*-Anregung mit Natrium-Licht vereinigt sich Xanthion (1) mit Acenaphthylen, Inden bzw. N-Phenylmaleinimid in guten Ausbeuten zu den Spirothietan-Derivaten 3, 7 bzw. 8. Die analogen Photoreaktionen (λ ≍ 400 nm) der 2-Thioparabansäure 4 in Gegenwart von Inden, Benzo[b]furan bzw. N-Phenylmaleinimid verlaufen unter Bildung der Spirothietane 6a, b bzw. 9. Spektroskopische Daten sichern die Konstitutionen.
