Tetrafluorothiophene S,S-dioxide, a highly reactive diene and dienophile, has been synthesized. A new route to 3,4-difluoro- and tetrafluorothiophene has been realized, and the previously unknown 2,3,4-trifluorothiophene has been obtained. The reactivity of tetrafluorothiophene S-oxide has been compared with that of the S,S-dioxide.
四氟噻吩 S,S-二氧化物是一种高反应性的二烯和亲二烯体，已经被合成出来。实现了一种新的制备 3,4-二氟和四氟噻吩的方法，并得到了以前未知的 2,3,4-三氟噻吩。四氟噻吩 S-氧化物的反应性已经与 S,S-二氧化物进行了比较。
