N-NO formation in 2-mercaptobenzothiazole

Dear All,

I have one query . 2-mercaptobenzothiazole can exist in tautomerism . In tautomerism stage, can its NH form N-No , As per literature, i understand that due to presence of Sulfur, it will form S-No and then proceed for S-S (Sulfide) dimer .Can you please check and share your comment on it .

Thanks ,

Amit
