Thianthrene

White to off-white solid

Thianthrene has been used to study aqueous solubilities of several solid nitrogen-, sulfur- and oxygen-containing heterocyclic derivatives of anthracene, phenanthrene and fluorene. It has been used in determination of partition coefficients of several sulfur-containing aromatics in 1-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide and supercritical carbon dioxide.

ChEBI: Thianthrene is the organosulfur heterocyclic compound that is the parent compound of the thianthrenes, a tricyclic structure comprising two benzene rings fused to the b and e sides of 1,4-dithin. It is a mancude organic heterotricyclic parent, an organosulfur heterocyclic compound and a member of thianthrenes.

Thianthrene was first synthesized by John Stenhouse by dry distillation of sodium benzenesulfonate. Thianthrene can be prepared by treating benzene with disulfur dichloride in the presence of aluminium chloride.

Thianthrene undergoes liquid phase tert-butylation in the presence of large pore zeolites and mesoporous aluminosilicates catalyst to yield tert-butyl derivatives. Thianthrene on oxidation in the presence of hydrogen peroxide and ligninase as catalyst from Phanerochaete chrysosporium yields thianthrene monosulfoxide.

thianthrene from Me2CO (charcoal), AcOH or EtOH. It sublimes in a vacuum. [Beilstein 19 H 45, 19 I 619, 19 II 34, 19 III/IV 347, 19/2 V 49.]
