complexes have been solved. The crystal structure of II confirmed the assigned structure and revealed existence of two sets of intermolecular C–H–Cl(M) type interactions, viz. (Ru)Cl–H–C(ferrocene) and (Ru)Cl–H–CHCl2. The air-stable, dark solid II is an efficient catalyst for ring-opening metathesis polymerization (ROMP) of cyclopentene, norbornene and cycloocta-1,5-diene. Electrochemical behavior of
的[(PCY治疗3)2氯2 RUCH-PH(我用乙烯基二茂铁)1和1二茂铁基-1,3-丁二烯2得到的固体产物。这些新配合物进行了表征1 H NMR,31 P NMR和13 C NMR光谱。两种配合物的X射线晶体结构均已解决。的晶体结构II证明给定的结构,并显示两组间C-H-CL(M)型的相互作用,即是否存在。(Ru)的CL-H-C(二茂铁)和(Ru)的CL-H-三氯甲烷2。空气稳定,深色固体II为环戊烯,降冰片烯和环辛-1,5-二烯的开环易位聚合(ROMP)的有效催化剂。该复合物的电化学行为清楚地反映了两个金属中心之间的电子通信。
