A kinetic study of the thermal irreversible isomerization of an isolable dialkylsilylene into the corresponding cyclic silene revealed that the activation enthalpy (ΔH‡) and entropy (ΔS ‡) are 18.49 ± 0.43 kcal mol-1 and -20.32 ± 1.35 cal mol-1 K-1, respectively. The relatively low ΔH‡ and negative ΔS‡ values are in accord with the concerted 1,2-silyl migration via a cyclic transition state as previously proposed. The cyclic silene in benzene-d6 isomerized photochemically into the corresponding alkenylsilane via 1,3-hydrogen shift.
