Thioureas react with activated arylfluoroides to give the corresponding diaryl sulphides. Octafluorotoluene, pentafluoronitrobenzene and 2,3,4,5-tetrafluoronitrobenzene afforded diaryl sulphides substituted para to the activating groups in good yield, whilst decafluoro-o-xylene, with two molecules of thiourea, gave 1,4,6,9-tetrafluoro-2,3,7,8-tetrakis(trifluoromethyl)thianthren. No reaction was observed

The reaction of the pentafluorobenzenethiolate ion with ethyl acetylenedicarboxylate gave a derivative of 4,5,6,7-tetrafluorobenzo[b]thiophen by a new, one-step cyclisationreaction. Other synthetic approaches to this ring system by conventional cyclisationreactions are presented.
