摘要: Nickelocene Ni(π-C5H5)2 reacts with triethylphosphite in dioxane at 50–70° to give Ni[P(OC2H5)3]4. Kinetic studies confirm a third-order rate law for this ligand substitution process the activation parameters Ea = 6.8 kcal/mole and ΔS≠ −53.8 e. u. The mechanistic implications of these results are discussed.
