资源简介：
The Lewis acid assisted triflate/methyl, azide/methyl,
and chlorine/methyl
exchange reactions between silicon and antimony have been studied
in the reaction of R(Me3Si)N–SbCl2 (R
= Ter) with AgOTf, AgN3, KOtBu, GaCl3, and Me3SiN3/GaCl3, resulting
in the formation of different methylantimony compounds. Furthermore,
R(Me3Si)N–SbCl2 (R = SiMe3) was reacted with GaCl3 at low temperatures to yield
a hitherto unreported amino(chloro)stibenium cation, the proposed
intermediate in methyl exchange reactions. Tetrachloridogallate salts
bearing different stibinostibonium cations such as [(Me3Sb)SbMe2]+ and [(Me3Sb)2SbMe]2+ along with the GaCl3 adduct of SbMe3 were isolated from such R(Me3Si)N–SbCl2/GaCl3 mixtures (R = SiMe3) at ambient
temperatures, depending on the reaction parameters.
