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, or through the dehydration of sulfonylamides. The reactivity of RSO2NSO2R compounds is largely dictated by the acidic nature of the N-H proton. They can be deprotonated by bases to form corresponding anions, which can then participate in various nucleophilic reactions. The stability and physical properties of RSO2NSO2R vary depending on the nature of the R groups. Electron-withdrawing R groups tend to increase acidity and potentially influence thermal stability. Applications for these compounds are found in organic synthesis, particularly as reagents for sulfonylation and as intermediates in the preparation of other sulfur-nitrogen containing compounds. Their specific utility often depends on the tailored properties conferred by the choice of R substituent.
