reaction of [Cr2O7]2− with p-bromothiophenol in dimethylformamide is the formation of the chromium(VI)-thioester [p-BrC6H4SCrO3]−, which has been isolated as the [Ph4As]+ salt and its structure determined by a single crystal X-ray diffraction study, thus confirming the proposed first step in the mechanism for the overall oxidation of thiophenols by dichromate.
