The thioacidazide reaction and its chemoselectivity were probed with alkyl azides for a potential application to form amide bonds in aqueous solvents. Our results reveal that under acidic conditions thioamides were formed as major reaction products suggesting a competing mechanism, whereas reactions forming amides predominated at slightly higher pH values.
