Краткое описание
A DFT study of a model reaction [(η5-C5H5)2MCH3]+ + RH ⇌ [(η5-C5H5)2MR]+ + CH4 (M = TiIV, ZrIV; R = Me, Et, Pr, Pri) was carried out with the PBE density functional. Exchange of σ-bonded ligand proceeds through the formation of agostic complexes [Cp2M(RH)CH3]+ followed by their isomerization into complexes [Cp2M(CH4)R]+ via an inner-sphere migration of a hydrogen atom. The calculated rate constants for such migrations involving the primary and secondary C--H bonds of propane molecule differ by 930 times for TiIV complexes and by 47 times for ZrIV complexes, which is due to the effect of steric factors.
