Popis:	A wide variety of aminoalkylsilanes (R3SiCR2NHR′) are rearranged to the isomeric alkylaminosilanes (R3SiNR′CHR2) by traces of n-butyllithium. It is shown that an equilibrium exists between the isomeric amide ions (N−) and carbanions (C−) which are involved as intermediates in the rearrangement. The values of the equilibrium constants were determined for several systems and in one case the rates and activation parameters were obtained for both the forward and reverse directions. The overall kinetics were also investigated for several systems and kinetic parameters were obtained. In some cases anion isomerization was the rate-controlling step; in other cases the rate-controlling step was the proton transfer between the starting amine and the carbanion which leads to product.
