The reaction of potassium thiocyanate with 1,2-dichloro-3,3-difluorocyclopropene in DMF leads to the formation of 1,2-dithiocyano- 3,3-difluorocyclopropene. In contrast, the reaction of sodium aryl- sulfinates with 1,2-dichloro-3,3-difluorocyclopropene or tetrachlorocyclopropene gave (E)-1,2-bis(arylsulfonyl)ethene as the only product.
硫氰酸钾与1,2-二氯-3,3-二氟环丙烯在DMF中的反应导致1,2-二硫氰基-3,3-二氟环丙烯的形成。相反,芳基亚磺酸钠与1,2-二氯-3,3-二氟环丙烯或四氯环丙烯的反应给出了(E)-1,2,2-双(芳基磺酰基)乙烯作为唯一产物。
