| 摘 要： | 含有亚硫酸四氟乙二醇酯(1)的四氟乙烷磺内酯(2)与H(CF_2)_4CH_2OH和三乙胺反应可获得草酸酯(CO_2CH_2CF_2CF_2—CF_2CF_2H)_2(3)。化合物(3)生成的机理解释为由于1的破环,生成了SOF_2和(COF)_2,后者进一步与H(CF_2)_4CH_2OH反应生成3。 3与二乙胺反应生成Et_2NCOCO_2CH_2(CF_2)_4H(4)。3和4皆为新化合物。

| Abstract: | A mixture of tetrafluoroethylene sulfite (1) and tetrafluoroethy-lene sultone (2) was reacted with H(CF_2)_4 CH_2OH in the presence of triethyl-amine to yield the oxalate (CO_2CH_2CF_2CF_2CF_2CF_2H)_2 (3).To explain themechanism of the formation of compound 3,ring cleavage of the cyclic tetra-fluoroethylene sulfite is proposed.In the ring cleavage,SOF_2 and (COF)_2 wereformed,the later further reacted with H (CF_2)_4 CH_2OH to produce 3.3 reactedwith diethylamine to give Et_2NCOCO_2CH_2(CF_2)_4H (4).both 3 and 4 are newcompounds. |
