WebStructure. The molecule is planar with a C=S double bond, so the name mercaptobenzothiazole is a misnomer.It is not a thiol, but instead is a thioamide, in the solid state, gas-phase, and in solution. A more appropriate name is benzothiazoline-2-thione.Solution measurements by NMR spectroscopy reveal no evidence for the thiol … WebSep 30, 2024 · However, by NMR characterization we revealed that sativin is in fact 1,3-thiazepane-2-thione, a tautomer of 4-mercaptobutyl isothiocyanate with 7-membered ring structure and so far unknown. This finding was further substantiated by conformation sampling using molecular modeling and total enthalpy calculation with density functional …
