Thiepine
In organic chemistry, thiepine (or thiepin) is an unsaturated seven-membered heterocyclic compound, with six carbon atoms and one sulfur atom. The parent compound, C 6 H 6 S is unstable and is predicted to be antiaromatic. Bulky derivatives have been isolated and shown by X-ray crystallography to have nonplanar C 6 S ring. Computational studies suggest that thiepine would eliminate a sulfur atom to form benzene. The intermediate is this process is the bicycle thianorcaradiene. In the complex with (η 4 -C 6 H 6 S)Fe(CO) 3 , the ring is stable. Benzothiepines have one fused benzene group and dibenzothiepines such as dosulepin and zotepine have two fused benzene groups. Damotepine is another thiepin derivative. .
