In an Arbuzov type reaction, amido phosphites (Et2N)2- PORand a broad range of halofluoro organic halides (X = Cl, Br) formed the corresponding alkylated derivatives R1–R2 [R1 = Bn, R2 = C(SO2F)3, CCl2F, CCl2CF3, CBr2F, C(CF3)3, C6F5; R1 = Et, CH2CF3, Me, R2 = CCl2CF3], whereas with FC(SO2F)3 and loss of SO2, BnCF(SO2F)2 was obtained, as shown by X-ray crystallography.
在阿尔布佐夫反应中,胺基磷酸酯(Et2N)2-POR和一系列氯氟有机卤化物(X = Cl, Br)形成了相应的烷基化衍生物R1–R2 [R1 = Bn,R2 = C(SO2F)3, CCl2F, CCl2CF3, CBr2F, C(CF3)3, C6F5;R1 = Et, CH2CF3, Me,R2 = CCl2CF3]。而使用FC(SO2F)3并失去SO2,则得到BnCF(SO2F)2,这一点通过X射线晶体学证实。
