摘要：

A stopped-flow investigation of the reversible addition of Ph3P to [(C8H11)Co(C5H5)]+ indicates the rate law, kobs = k1[Ph3P] + k-1. The low Δ† of 21.0 ± 1.2 kJ mol-1 and the negative ΔS† of -114 ± 5 J K-1 mol-1 are consistent with rapid addition to the enyl ligand. The higher Δ† of 86.2 ± 5.1 kJ mol-1 and the positive ΔS† of +60 ± 17 J K-1 mol-1are as expected for the reverse dissociation. Preliminary studies show that the related complex [(C7H9)Co(C5H5)]+ is at least 65 times more electrophilic towards Ph3P. © 1979.
