We succeeded in synthesising and characterising a new heterogeneous hybrid ruthenium catalyst that exhibits excellent stability, reusability and leaching characteristics. The host–guest interaction is studied by XRD, XRF, ICP/MS, BET, FT-Raman and solid state NMR analysis. Moreover, we tested this catalytic system in ring-closing metathesis (RCM), ring-opening metathesis polymerization (ROMP), Kharasch addition, atom transfer radical polymerization (ATRP) and vinylation reactions. The results obtained from these tests show that for ROMP, RCM, Kharasch addition and vinylation reactions the heterogeneous catalyst possesses important advantages in comparison with its homogeneous analogue.
我们成功合成并表征了一种新型的异质混合钌催化剂,该催化剂表现出优良的稳定性、可重复使用性和浸出特性。通过XRD、XRF、ICP/MS、BET、FT-Raman和固态NMR分析研究了宿主–客体相互作用。此外,我们在环闭合交叉反应(RCM)、环打开交叉聚合(ROMP)、卡拉什加成、原子转移自由基聚合(ATRP)和乙烯化反应中测试了该催化系统。测试结果表明,在ROMP、RCM、卡拉什加成和乙烯化反应中,该异质催化剂相比其均相类似物具有重要优势。
