ArW of thiophenols. Reaction of l, 4-dichlorobenzene with the sodium salt of tert-butyl mercaptan gave compounds 2 and 3 in yields of 89 and 7%, respectively. Thiophenol3 was probably formed from 2 by elimination of isobutene rather than by nucleophilic substitution since no di-tert-butyl sulfide was observed.
