Perfluoro-2-methyl-2-pentene was successfully converted to perfluoro-(1,1-dimethylbutyl)methyl ethers by vic-oxymethylfluorination with chloromethyl ethers in the presence of KF in aprotic polar solvents such as N,N-dimethylformamide and N-methylpyrrolidone. By the addition of a catalytic amount of quaternary ammonium salt, the reaction was accelerated and the yield of product greatly increased.
全氟-2-甲基-2-戊烯成功地被转换为全氟- (1,1-二甲基丁基)的甲基醚VIC -oxymethylfluorination与氯醚在KF在非质子极性溶剂如存在N,N-二甲基甲酰胺和ñ -甲基吡咯烷酮。通过加入催化量的季铵盐,反应得以加速,产物的产率大大提高。
