The cyclic chlorophosphazenes NnPnCl2n(n= 3–6) are fluorinated by a mixture of SbF3 and SbCl5 to give either the monofluoro-compound or, depending on the reagent ratio, mixtures of non-geminal chloride fluorides. The n.m.r, parameters of the monofluorides show similar ring-size effects to the monochlorofluorocyclophosphazenes.
通过SbF 3和SbCl 5的混合物将环状氯代磷腈N n P n Cl 2 n(n = 3–6)氟化,得到单氟化合物,或者取决于试剂的比例,得到非双基氯氟化物的混合物。一氟化物的nmr参数显示出与一氯氟环磷腈类似的环尺寸效应。
