Pyrolysis (900 K) of cyclopenteno-1.2,3-thiadiazole with trapping of the products in argon at 20 K gave ethylene and propadienethione. Small quantities of thioketene and trimethylenethioketene were also formed. The infrared bands due to propadienethione were identified by their disappearance on irra
