โœฆ Synopsis


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 Frequently, a small amount of biaryl is also produced. We have

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
