摘要：

A stopped-flow investigation of the additions of n-BU3P and Ph3P to the ethylene ligand in [(η-C5H5)Fe(CO)2(η2-C2H4)]+ (I) reveals the general rate law, kobs k [R3P]. This is consistent with direct addition, as is the negative ‡Sm ‡ of -63 ± J K-1 found for the Ph3P reaction. The relatively low reactivity of I towards Ph3P compared with other π-hydrocarbon complexes is seen to arise from its relatively high ‡HDG value of 42.4 ± 1.4 kJ mol-1. © 1979.
