Synthesis of 3H-1,2-dithiole-3-thiones by a novel oxidative cyclization
摘要:
Reaction of 3-oxo dithioic acids with a combination of hexamethyldisilathiane and N-chlorosuccinimide in the presence of a catalytic amount of imidazole brings about oxidative ring closure to 3H-1,2-dithiole-3-thiones. Yields vary from poor to good.
Exposure of 3-oxo dithioic acids to a solution of polysulfanes in liquid hydrogen sulfide gives 3H-1,2-dithiole-3-thiones in yields varying from poor to excellent. The method tolerates the presence of functional groups which are problematical for other methods of synthesis.

The novel title heterocycle, which was prepared in three steps and is the last possible isomer of the C4X6(X = chaclogen) group, exhibits unusual 13C n.m.r. line broadening and a shortintramolecular nonbonded S–O distance as well as extremely short intermolecular contacts in the solid state, as determined by X-ray crystallography.
新的标题杂环经三个步骤制备,是C 4 X 6(X =硫菌素)基团的最后一种可能的异构体,具有异常的13 C nmr线展宽和短的分子内非键合S–O距离,以及极高的通过X射线晶体学确定的固态短分子间接触。
