本文研究了FO_2SCF_2COF、HFPO和HFP在F~(?)催化下的三元加成反应。我们发现在反应开始时存在着一个反应速度增长的过程,这个过程的长短受溶剂的用量和反应温度的影响。 (CF_3)_2CFCOCF(CF_3)OCF_2CF_2SO_2F只有在5℃以上和乳化催化剂的存在下才生成。通过~(19)F NMR的研究,我们认为FO_2SCF_2COF、HFPO和HFP对于F~(?)的反应活性存在如下的顺序: FO_2SCF_2COF>HFPO>HFP
In this paper, the ternary addition reaction of FO_2SCF_2COF, HFPO and HFP under F? (?) Catalysis was studied. We found that at the beginning of the reaction there was a process of increasing the reaction rate, the length of which depends on the amount of solvent and the reaction temperature. (CF_3) _2CFCOCF (CF_3) OCF_2CF_2SO_2F is only formed above 5 ° C and in the presence of an emulsion catalyst. The ~ (19) F NMR studies suggest that the order of F_2 (?) Reactivity of FO_2SCF_2COF, HFPO and HFP is as follows: FO_2SCF_2COF> HFPO> HFP
