Synthesis and structure

edit

It is prepared by treating aniline with thionyl chloride:[4]

3 PhNH2 + SOCl2 → PhNSO + 2 [PhNH3]Cl

X-ray crystallographic analysis confirms that N-sulfinylaniline is structurally related to sulfur dioxide as well as sulfur diimide. The C–S=N=O dihedral angle is –1.60°.[5]
