RSO2NSO2R
RSO2NSO2R, also known as disulfuryl diamide, is an inorganic compound with the chemical formula (RSO2)2NH where R typically represents an alkyl or aryl group. This class of compounds can be considered as the imide of disulfuric acid, with the hydrogen atom of the imide group replaced by two sulfonyl groups. The structure features a central nitrogen atom bonded to two sulfur atoms, each of which is double-bonded to two oxygen atoms and single-bonded to the R group. The presence of the electron-withdrawing sulfonyl groups significantly increases the acidity of the N-H proton compared to simple amides or imides.
These compounds are generally synthesized by the reaction of sulfonyl chlorides with ammonia or primary amines,
