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.

Abstract: Methods for producing triflazoles or related derivatives thereof, and the resulting products are provided. For example, triflazoles can be prepared by reaction of trifluoromethanesulfonyl fluoride with an azole or azolate salt. Yields up to 78% are obtained. Triflazoles can be prepared by the reaction of a trifluoromethanesulfonyl fluoride with an N-silylazole in the presence of a basic catalyst. Yields up to 97% are obtained.

Abstract: Dimethylamine (Me2NH) is reacted with sulfuryl fluoride (SO2F2) to form at least a first phase comprising N-(fluorosulfonyl) dimethylamine (FSO2NMe2), tetramethylsulfamide (SO2(NMe2)2), or a combination thereof. A second phase, which may include dimethylamine hydrofluoride (Me2NH2F), may be also formed and separated from the first phase. FSO2NMe2 or SO2(NMe2)2 is then isolated from the first phase. For example, the first phase may be a liquid phase, and FSO2NMe2 and SO2(NMe2)2 are separated by distillation, optionally under reduced pressure.

Abstract: The present invention is directed to methods for preparing a fluorosulfonate ester or a salt thereof, through a reaction of a dissolved sulfonyl fluoride (RFSO2F) with alkoxide anion (RO?) optionally in the presence of an aprotic base (B), where RF is fluorine or a C1-C8 perfluoroalkyl group, and R is a primary alkyl or alkoxyalkyl. Alkoxide anion (RO?) can be generated from a precursor such as an alcohol or silyl ester.

Abstract: The present invention is directed to methods comprising adding ammonia, either as an ammonium salt or as a gas at pressures below 0.01 MPa, to a sulfuryl fluoride solution to form the anion of bis(fluorosulfonyl)amine under conditions well suited for large-scale production. The bis(fluorosulfonyl)amine so produced can be isolated by methods described in the prior art, or isolated as an organic ion pair, such as an alkylammonium solid salt, or as an ionic liquid.
