A completely fluorinated ester of the type RFCO2CF2RF′ was obtained from reaction of silver 3,6,9-trioxa-F-undecanoate and iodine with a diluent at 130°. This new substance resembled closely the previously prepared 1,1-dichloro-F-alkyl esters and was hydrolytically and thermally labile. Substitution products, RFCOY (Y = nucleophile) and pyrolysis products, RFCOF and RF′COF were isolated and characterized
由3,6,9-三氧杂-F-十一酸银和碘与稀释剂在130°C下反应制得R F CO 2 CF 2 R F '型的完全氟化酯。这种新物质非常类似于先前制备的1,1-二氯-F-烷基酯,并且水解和热不稳定。取代产物,R ˚F COY(Y =亲核)和热解产物,R ˚F COF和R ˚F 'COF进行分离和表征。似乎酰基次碘酸盐和碘代-F-烷烃通过S E i型过程反应生成了完全氟化的酯。
