General structure of an N-sulfinyl amine
N-Sulfinylaniline is a common sulfinylamine

Sulfinylamines (formerly N-sulfinyl amines) are organosulfur compounds with the formula RNSO where R = an organic substituent. These compounds are, formally speaking, derivatives of HN=S=O, i.e. analogues of sulfur dioxide and of sulfur diimide. A common example is N-sulfinylaniline. The S-N bond in sulfinylamines is a dienophile.[1] They undergo [2+2] cycloaddition to ketenes.[2]

According to X-ray crystallography, sulfinylamines have planar C-N=S=O cores with syn geometry.[3]

Preparation

Sulfinylamines can be made when thionyl chloride SOCl2 reacts with a primary amine.[4] Indeed, the parent, thionylimide (HNSO), can be made that way at low temperature[5] or in the gas phase. Under standard conditions it polymerizes.[6] The corresponding trimethylsilyl compound, Me3SiNSO, is a stable liquid, albeit air-sensitive, and a common "NSO" synthon.[7]

Reactions

A frustrated Lewis pair, such as tris(tert-butyl) phosphine and tris(pentafluorophenyl)borane, can attach to the NSO chain to yield a R'3P=N+(R)SOBR"3 compound.[4]
