Thioxanthene is a chemical compound from the group of heterocycles and polycyclic aromatic hydrocarbons in which a carbon atom has been replaced by a sulfur atom in the middle of the three rings .
Extraction and presentation
Thioxanthene can be obtained by condensing thiophenol and o- aminobenzoic acid in polyphosphoric acid or by reacting thiophenol with toluene at 450 to 650 ° C.
use
Derivatives of thioxanthene that differ at R 1 and R 2 , like the very similar phenothiazines, are used in medicine as neuroleptics .
Important representatives are Chlorprothixen , Zuclopenthixol / Clopenthixol and Flupentixol . Chlorprothixen has an open side chain , Flupentixol and Zuclopenthixol have a piperazinylalkyl side chain .
