Mercaptoheteroarenes (1) underwent electrophilic cyanation with p-toluenesulfonyl cyanide (TsCN) in THF in the presence of NaH to give the corresponding thiocyanatoheteroarenes (2) in moderate to good yields. In DMF, tosylheteroarenes (4) were formed by substitution with p-toluenesulfinate ion through thiocyanatoheteroarenes (2).
