Derivatives of bicyclo[4.2.O]octa-2,4,'7-triene (I) have been invoked as intermediates in the light-induced formation of cycle-octatetraenes from certain acetylenes and benzene (1,2,3) or benzonitrile (4) as well as in the photochemical synthesis of 1:l adducts[e.g., (II)1 from tolan (diphenylacetyl

## Abstract Die cyclischen Schwefelsรคureester **4a, d** und **e** werden aus **1a, d** und **e** mit Schwefelsรคure bei Raumtemperatur dargestellt. Bei hรถherer Temperatur entstehen die Diketone **3a** oder **b**. Sowohl die Thermolyse der Schwefelsรคureester bei 180โ200ยฐC als auch ihre Sรคurehydrolyse
