The reaction of 1- and 2-naphthols 1 and 2 with a variety of thiols 3 in the presence of trifluoromethanesulfonic acid afforded naphthyl alkyl and aryl sulfides 4 and 5, respectively, in good yields. Similarly naphthyl bis(alkyl) or bis(aryl) sulfides 10-13 were prepared from the corresponding dihydroynaphthalenes 6-9.

An electrochemical carbenoid insertion reaction of diazo compounds into C–S and C–O bonds with electricity as the oxidant has been reported in this work. In this protocol, this transformation proceeded smoothly under mild conditions at room temperature in the absence of a catalyst and a ligand. In addition, the yield of the S–H insertion product was up to 96% and the O–H product could be efficiently
