Di-2-pyridyl sulfite is a very usefulreagent for the preparation of N-sulfinylamines, nitriles, isocyanides, and carbodiimides in high yields under essentially neutral conditions.
Aromatic and aliphatic N-sulphinyl amines add smoothly to diphenyl and biphenylene ketene forming substituted 1,2-thiazetidinone-(3)-oxides-(1). An addition of ketene itself to N-sulphinyl cyclohexyl amine can be concluded from secondary products only.

Treatment of amine derivatives such as amines, sulfonamides, and amides with N,N′-sulfinylbisimidazole and N-(chlorosulfinyl)imidazole respectively gives the corresponding N-sulfinylamine derivatives (); the latter reaction using N-(chlorosulfinyl)imidazole yields in almost quantitative yields at 20°C under mild conditions.

The reactions of diphenylcyclopropenone with N-sulfinylanilines in the presence of nickeltetracarbonyl gave pyrrolines, 1,3,4-triphenylpyrroline-2,5-dione (IIIa) and 1-p-tolyl-3,4-diphenylpyrroline-2,5-dione (IIIb). In these reactions, exchanges of C=O for S=O were observed. On the other hand, the reaction with N-sulfinylcyclohexylamine gave a 1:1 cycloadduct, 2-cyclohexyl-4,5-diphenyl-3-isothiazolone-1-oxide

An iron-catalyzed photochemical sulfinamidation of hydrocarbons with N-sulfinylamines has been developed. The merger of ligand-to-metal charge transfer (LMCT) of FeCl3 with hydrogen atom transfer (HAT) process is the key for the generation of alkyl radicals from hydrocarbons, and the resultant alkyl radicals were readily trapped by N-sulfinylamines to produce structurally diverse sulfinamides.
