The reactions of bromonaphthalenediazonium tetrafluoro-borates (6a,b and 11a,b) with sodium benzenethiolate in DMSO give, through the preliminary formation of the corresponding diazosulfides (7a,b and 12a,b), bis(phenylthio)naphthalenes (8a,b and 13a,b) deriving from substitution of both the diazo group and the bromine. Isolated diazosulfides (7a,b and 12a,b) likewise furnish satisfactory yields of
