Abstract
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 azolate salt, an N-silylazole, or a combination thereof. Symmetric and asymmetric sulfonyldiazoles are obtained by further reaction of such an N-(fluorosulfonyl)azole with azoles, azolate salts, or N-silylazoles. A sulfonyldiazole can be also produced by reacting sulfuryl fluoride with an azole, an N-silylazole, or a combination thereof in one pot.
Claims21
A method, comprising:
- reacting sulfuryl fluoride (SO2F2) with an azole or an azolate salt having a first azole base structure (Azole 1), wherein Azole 1 in a free form is protic;
- and
- isolating an N,N′-sulfonylbisazole (Azole 1-SO2-Azole 1).
A method, comprising:
- reacting an N-(fluorosulfonyl)azole (Azole 1-SO2F) having a first azole base structure (Azole 1) with a protic azole or an azolate salt having a second azole base structure (Azole 2), wherein each of Azole 1 and Azole 2 in a free form is protic;
- and
- isolating an N,N′-sulfonylbisazole (Azole 1-SO2-Azole 2),
- wherein the first and the second azole base structures are independently selected from the group consisting of imidazole, pyrazole, 1,2,4-triazole, benzimidazole, benzotriazole, indazole, 2-methylimidazole, 2-methylbenzimidazole, and 3,5-dimethylpyrazole.
