Abstract

The substituent migration on the X2Y rings (X, Y=C, Si, Ge) was studied by theoretical method with silyl and hydrogen substituents and it was found that all the reactions (with the exception of cyclopropene) proceed in a two-step mechanism via a stable intermediate. The rate determining step of the reaction is the first step. The barrier of the second step is small and the energy of the intermediate is close to that of the reactant. Both the first transition state (T1) and the intermediate (I) are of monobridge structures of different types. Since the intermediate bridge structure is almost as stable as the product, it may be observed in the substituent migration reactions.
