The present disclosure provides methods for producing N-(fluorosulfonyl)azoles, sulfonyldiazoles, or related derivatives thereof; and the related products including N-(fluorosulfonyl)azoles, sulfonyldiazoles, and related derivatives thereof. For example, an N-(fluorosulfonyl)azole is obtained by reaction of sulfuryl fluoride with an azoles, an azole anion compound, a silylazole, or a combination thereof. Symmetric and asymmetric sulfonyldiazoles are obtained by further reaction of such an N-(fluorosulfonyl)azole with azoles, azole anion compounds, or silylazoles. A sulfonyldiazole can be also produced by reacting sulfuryl fluoride with an azole, a silylazole, or a combination thereof in one pot.

Easily accessible 1,1'-sulfonylbis(benzotriazole) (Bt(2)SO(2), 1) reacts with secondary amines at room temperature to afford (i) the corresponding o-sulfamidotriazobenzenes 2a-d (53-75%) via concurrent substitution of the first and ring opening of the second benzotriazolyl group and (ii) N-sulfonylbenzotriazoles 3b, c, e, f (7-73%). 1-(Morpholine-4-sulfonyl)-1H-benzotriazole 3c reacts with piperidine, pyrolidine, and N-methylpiperazine under microwave irradiation (120 W) at 120 degrees C for 10 min to give the unsymmetrical sulfamides 4a-c (80-90%).
