chloridate [(CH3)2CF3CO]2P(O)Cl reacted with methanol, ethanol and propanol, but not with isopropanol – even on heating in the presence of the catalyst 4-dimethylaminopyridine – due to steric hindrance at phosphorus. The relative reactivities of three of the chloridates decreased in the order [(CF3)2CHO]2P(O)Cl > [(FCH2)2CHO]2P(O)Cl > [(CH3)2CF3CO]2P(O)Cl. Also described is the synthesis of phosphates (CF3CH2O)2P(O)OCH2R
通过处理磷酰氯(R F O)2 P(O)Cl(其中R F为HCF 2 CH 2),制得29个双(氟烷基)磷酸酯(R F O)2 P(O)OR,产率为18-75%。 HCF 2 CF 2 CH 2,H(CF 2)4 CH 2,C 2 F 5 CH 2,C 3 F 7 CH 2,(CF 3)2 CH,(FCH 2)2 CH和(CH 3)在三乙胺的存在下,在乙醚中用甲醇,乙醇,丙醇和异丙醇制得2 CF 3C。体积大的氯化物[(CH 3)2 CF 3 CO] 2 P(O)Cl与甲醇,乙醇和丙醇反应,但与异丙醇不反应,即使在催化剂4-二甲基氨基吡啶存在下加热也是如此,这是由于在室温下的空间位阻磷。三种氯化物的相对反应性按[(CF 3)2 CHO] 2 P(O)Cl> [(FCH 2)2 CHO] 2 P(O)Cl> [(CH 3)2 CF 3的顺序降低。CO]2 P(O)Cl。还描述了磷酸盐(CF 3
