product in each being a mixture of (Me3Si)2C(SiEt2Cl)(SiMe2F) and (Me3Si)2C(SiEt2F)(SiMe2Cl), and analogous migration of N3 occurs in the corresponding reaction of (Me3Si)2C-(SiEt2N3)(SiMe2Br). Anchimeric assistance by the N3 group facilitates the solvolysis of (Me3Si)2C(SiMe2N3)(SiMe2Br).
的氯取代基的迁移发生时(ME 3 Si)的2 C(森达2 Cl)的(SIET 2 I)或(ME 3 Si)的2 C(SIET 2 Cl)的(森达2 I)发生反应以的AgBF 4,产品由于各自为(Me 3 Si)2 C(SiEt 2 Cl)(SiMe 2 F)和(Me 3 Si)2 C(SiEt 2 F)(SiMe 2 Cl)的混合物,N 3在(Me 3 Si)2 C-(SiEt 2N 3)(SiMe 2 Br)。N 3基团的手性协助促进了(Me 3 Si)2 C(SiMe 2 N 3)(SiMe 2 Br)的溶剂化。
