compounds, CP(CO)nM-CH(CH3)C6H5 (n = 2, M Fe, Ru; n = 3, M Mo, W), in benzene, in the absence and presence of free radical traps, yielded the following values of ΔH‡ (kcal/mol) for the homolytic bond dissociation reactions, Cp(CO)nM-CH(CH3)C6H5 → Cp(CO)nM· + ·CH(CH3)C6H5: Fe, 29.6; Ru, 34.6; Mo, 26.6; W, 30.6. The corresponding M-CH(CH3)C6H5 bond dissociation energies were deduced to be 28, 33, 25 and
阐明了一系列化合物CP(CO)n M-CH(CH 3)C 6 H 5(n = 2,MFe,Ru; n = 3,MMo,W的产物和热分解动力学),在苯中不存在和存在自由基陷阱的情况下,均聚键解离反应的Cp(CO)n M-CH(CH 3)C 6 H的ΔH ‡(kcal / mol)为以下值5 →Cp(CO)n M·+·CH(CH 3)C 6 H 5:Fe,29.6; n,6。茹34.6; 莫26.6; W,30.6。相应的M-CH(CH 3)C6 H 5键解离能分别推导为28、33、25和29 kcal / mol。
