The reaction of a triarylsulfonium halide with a sodium alkoxide in a eolution in the corresponding alcohol at en elevated temperature produces a mixture of aramatlc hydrocarbon, alkyl aryl ether, diary1 sulfide and aldol resin (or a ketone if the alkoxlde ie derived from a secondary alcohol).i,2 Fr

In a previous cozmmmication (1) we have suggested that the mechanism of pyrolysis of triarylsulf~ium halides to give diary1 sulfides snd the corresponding aryl halides involves the additlcn of the halide ion to the sulfur atom of the sulfonium cation and subsequent intramolecular collapse of the add
Diphenyliodonium tetrafluoroborate and diphenyliodonium hexafluorophosphate have been found to generate u p to two equivalents of hydrogen fluoride per equivalent of the iodonium salt by pyrolysis at 239ยฐC in the neat state and at 150ยฐC in the presence of anisole or nitrobenzene.
