Immobilized catalysts were prepared by mixing the ligand Cp′, [C₅Me₄(n-propyl-Si(OEt)₃)], with RhCl₃·xH₂O for subsequent reaction with silica Aerosil 200 (system A) or by copolymerization with TEOS (system B). Both systems were applied on olefin hydrogenation, showing high activity and robustness, allowing for many recycles (TON = 1.0 × 10⁵ for system A and 2.0 × 10⁴ for system B). The characterization techniques (IR-DRIFTS, ¹³C-CPMAS, and TEM) suggest a molecular nature for catalytic species. According to the deuteration experiment, a tetra-hapto-Cp′-Rh would be formed on the surface during the catalytic runs.

通过将配体Cp'，[C ₅ Me ₄（n-丙基-Si（OEt）₃）]与RhCl ₃ ·xH ₂ O混合以随后与二氧化硅Aerosil 200（系统A）反应或通过共聚反应来制备固定化催化剂使用TEOS（系统B）。两种系统均用于烯烃加氢，显示出高活性和稳健性，可进行许多次循环（系统A的TON = 1.0×10 ⁵，系统B的= 2.0×10 ⁴）。表征技术（IR-DRIFTS，¹³ C-CPMAS和TEM）表明了催化物质的分子性质。根据氘化实验，在催化过程中会在表面形成四-Cp'-Rh。
