Product Description
1-(Fluorosulfonyl)-2,3-dimethyl-1H-imidazol-3-ium trifluoromethanesulfonate (Cas Number 2179072-33-2) is a solid fluorosulfuryl imidazolium triflate salt (SuFEx-IT).
It's often used as an alternative to sulfuryl flouride (SO2F2), which can be difficult to access given its complex handling procedures, and can be used to convert amines and phenols to fluorosulfates and sulfamoyl fluorides.
These can be utlised as a pseudohalide in Pd-catalysed cross-coupling reactions, and are commonly used in biological studies and medicinal chemistry.
