The rate of replacement of the halogen atom in isomers of RC6F4X (X=Cl, Br, or I) by the SiMe3 group under the action of Me3SiCl and P(NEt2)3 depends on the nature and the mutural arrangement of the substituents X and R. In addition to silyldehalogenation, compounds C6HF4X (X=Br or I) undergo silyldeprotonation and reduction to tetrafluorobenzenes.
在 Me3SiCl 和 P(NEt2)3 的作用下,SiMe3 基团对 RC6F4X 异构体(X=Cl、Br 或 I)中卤素原子的置换率取决于取代基 X 和R. 除了甲硅烷基脱卤之外,化合物 C6HF4X(X=Br 或 I)还会发生甲硅烷基脱质子化并还原为四氟苯。
