N-Sulfinylaniline is the organosulfur compound with the formula C6H5NSO. It is a straw-colored liquid. N-Sulfinylaniline is an example of a sulfinylamine, a heterocumulene. It is a dienophile[1] and a ligand in organometallic chemistry.[2]
Synthesis and structure
It is prepared by treating aniline with thionyl chloride:[3]
- 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°,[4]
