Guaiazulene reacted with reactive sulfuration reagents to give guaiazulenopentathiepin together with a 1,2-dithiin compound and a mixture of bis(guaiazulyl)sulfides. The yield of the pentathiepin was improved by the reaction with the reagent prepared from sulfur chloride and imidazole in a molar ratio of one to two. Reduction of the pentathiepin and the successive reaction with N,N'-(thio)carbonyldiimidazoles afforded 2-(thi)oxo-1,3-dithioles.
