Abstract

The enthalpies of reaction of a fluorous tertiary phosphine, P(CH2CH2(CF2)5CF3) 3 (PRf3) 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)(PRf3)2 and Cp′Ru(PRf3)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.
