资源简介：
Silylenecyclotetrasilane 4 synthesized as marginally stable orange crystals undergoes ring expansion to give cyclopentasilene 5 quantitatively with the activation parameters of ΔH⧧ = 24.8 ± 1.0 kcal mol−1 and ΔS⧧ = +6.5 ± 3.2 cal mol−1 K−1. The activation parameters and DFT calculations support that the isomerization of 4 to 5 proceeds through stepwise double 1,2-silyl migrations.
