Kineticstudies on the interconversion between trans-RhCl(FcC⋮CSiMe3)(PPri3)2 (2a) and trans-RhClCC(Fc)(SiMe3)}(PPri3)2 (3a) (Fc = ferrocenyl group) provided the following activation parameters for the forward and the backward reactions: ΔH⧧ = 19.8 ± 0.2 kcal mol-1 and ΔS⧧ = −4.8 ± 0.7 eu for 2a to 3a and ΔH⧧ = 22.7 ± 0.1 kcal mol-1 and ΔS⧧ = −8.6 ± 0.4 eu for 3a to 2a. The values are consistent
反式RhCl(FcC ⋮CSiMe 3)(PPr i 3)2(2a)与反式RhCl C C(Fc)(SiMe 3)}(PPr i 3)2(3a)(Fc)互变的动力学研究=二茂铁基),用于所述前向和后向反应提供了以下激活参数:Δ ħ ⧧ = 19.8±0.2千卡摩尔- 1和Δ小号⧧ = -4.8±0.7 EU对于图2a至图3a和Δ ħ ⧧ = 22.7±0.1大卡摩尔-1和Δ小号⧧ = -8.6±0.4 EU为图3a到图2a。该值与通过SiMe 3基团的1,2-迁移引起的异构化机理是一致的。
