티옥산텐-9-온 C화학적 특성, 용도, 생산

개요

Thioxanthone is a heterocyclic compound that is a sulfur analog of xanthone.
Thioxanthone can be prepared by the reaction of diphenyl sulfide with phosgene in the presence of catalytic aluminium chloride. This synthesis can be seen as a special case of the Friedel-Crafts acylation. The reduction product is thioxanthene.
Thioxanthone dissolves in concentrated sulfuric acid to give a yellow colored liquid with intense green fluorescence. A mixture of the thioxanthone derivatives of 2- and 4-isopropylthioxanthone (ITX) is used in the printing industry. Pharmaceutical drugs that are derivatives of thioxanthone include hycanthone and lucanthone.

화학적 성질

slightly yellow crystalline powder

용도

Thioxanthen-9-one is a reagent and a starting material for the synthesis of Metixene Hydrochloride. It is also used for highly functional group tolerant and chemoselective oxidation of aromatic or aliphatic sulfides to sulfoxides with hydrogen peroxide.

Purification Methods

It forms yellow needles from CHCl3 or EtOH and sublimes in vacuo. It is soluble in CS2, hot AcOH, and dissolves in conc H2SO4 to give a yellow colour with green fluorescence in VIS light. The sulfone has m 187o (from EtOH), and the hydrazone has m 115o (yellow leaflets from EtOH/*C6H6). The oxime has m 194-196o (from pet ether). [Szmant et al. J Org Chem 18 745 1953, Ullmann et al. Chem Ber 49 2509 1916, NMR: Sharpless et al. Org Magn Res 6 115 1974, Beilstein 17 H 357, 17 I 191, 17 III/IV 5302, 17/10 V 437.]

Structure and conformation

Thioxanthen-9-one (TX) is a aromatic ketone. In comparison with other aromatic ketones, TX has a high triplet energy and a relatively long triplet lifetime, while it has the ability to participate successfully in merger reactions with metal complexes. The conformation of TX is not fixed, but it interconverts from a planar (C2v) to a non-planar conformation. In the case of TX, the intersystem crossing of an electron normally occurs from a non-bonding orbital (n) to an anti-bonding pi orbital (π*) (nπ* configuration) and occurs 103 times faster than in the case of migration from the same type of molecular orbital (ππ* migration).Theoretical studies support that TX's low lying triplet state is close enough to the singlet state, favoring in this way internal conversion (IC) and ISC upon photoexcitation. Due to its high triplet energy, TX is an efficient sensitizer for oxygen, leading to singlet oxygen, since the excitation of oxygen requires around 23 kcal mol^-1[1].
