SULFONYLDIAZOLES AND N-(FLUOROSULFONYL)AZOLES, AND METHODS OF MAKING THE SAME
-
Paragraph 0148, (2020/10/21)
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.

Application of activated phenol fluorosulfates as substrates in a Pd/NBE mediated sequential alkylation-arylation, commonly known as a Catellani reaction, is presented. These substrates provide a level of complementarity to the commonly used aryl halides and, in combination with a plethora of existing Catellani reaction variations, enable even wider application of this powerful synthetic tool.

A convenient transformation of phenols into the corresponding aryl fluorosulfates is presented: the first protocol to completely circumvent direct handling of gaseous sulfuryl fluoride (SO2F2). The proposed method employs 1,1'-sulfonyldiimidazole as a precursor to generate near-stoichiometric amounts of SO2F2 gas using a two-chamber reactor. With NMR studies, it was shown that this ex situ gas evolution is extremely rapid, and a variety of phenols and hydroxylated heteroarenes were fluorosulfated in good to excellent yields.
