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.
