Displacement of the THF solvent molecule from (η5-C5H5)Mn(CO)2THF by simple two electron donor ligands: evidence for a dissociative mechanism and determination of the Mn–THF bond strength Academic Article uri icon


  • The reaction between CpMn(CO)2THF (Cp=η5-C5H5, THF=tetrahydrofuran) and nitrogen containing ligands is studied in THF solution. In all cases the products of the reaction are the known CpMn(CO)2L complexes (L=piperidine, 4-acetylpyridine). The reaction of the solvated complex with both ligands studied proceeds through a purely dissociative mechanism. In good agreement with previous thermochemical measurements, kinetic analysis yields an average value of 24.0±3.0 kcal mol-1 for the CpMn(CO)2-THF bond dissociation energy. The results of the present study clarify the relationship between metal-solvent bond strengths obtained by kinetic methods and those obtained by thermochemical measurements. © 1999 Elsevier Science S.A.
