| Abstract: | Migration of the Cl substituent takes place when (Me3Si)2C(SiMe2Cl)(SiEt2I) or (Me3Si)2C(SiEt2Cl)(SiMe2I) reacts with AgBF4, the 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). |
