Abstract
The enthalpies of reaction of [Rh(CO)(2)Cl](2) (1) with a series of monodentate tertiary phosphine ligands, leading to the formation of RhCl(CO)(PR(3))(2) complexes, have been measured by anaerobic solution calorimetry in CH2Cl2 at 30.0 degrees C. These reactions are rapid and quantitative. The measured reaction enthalpies span a range of 43 kcal/mol. The relative stability scale established is as follows: P(NC4H4)(3) < P(NC4H4)(2)(C6H5) < P(OPh)(3) < P(p-CF3C6H4)(3) < P(NC4H4)(C6H5)(2) < P(p-ClC6H4)(3) < AsEt(3) < P(p-FC6H4)(3) < PPh(3) < P(p-CH3C6H4)(3) < P(p-CH3OC6H4)(3) < PPh(2)Me < P(OMe)(3) < PPhMe(2) < PEt(3). The relative importance of phosphine electronic ligand parameters is closely examined in terms of the presented quantitative thermochemical information. Comparisons with enthalpy data in related organometallic systems are also presented.
