Abstract

The enthalpies of reaction of a fluorous tertiary phosphine, P(CH₂CH₂(CF₂)₅CF₃) ₃ (PR_f3) with [Rh(CO)₂Cl]₂ (1) and Cp′Ru(COD)Cl (Cp′ = η⁵-C₅H₅ (2), η⁵-C₅Me₅ (3)), leading to the formation of RhCl(CO)(PR_f3)₂ and Cp′Ru(PR_f3)₂Cl complexes have been measured by anaerobic solution calorimetry in THF at 30.0°C. These reactions are rapid and quantitative. The measured reaction enthalpies allow for a quantitative determination of characteristic phosphine steric and electronic parameters associated with this novel tertiary phosphine ligand. Sterically, the P(CH₂CH₂(CF₂)₅CF₃) ₃ ligand appears identical to PEt₃.
