Abstract
The structures of the intermediate 1,4-diaryl-2-chloro-1,4-dioxo-butane-2,3-disulphenyl chloride formed in the reaction of an acetophenone derivative with thionyl chloride and of the follow-up products, 1,4-diaryl-1,4-dioxo-butene-2,3-disulphenic acid diethyl ester and anilide 7 and 8 are called in question. More reliable structure for the compounds are proposed.
