[Rh(PiPr3)2Cl]2 reacts with various small molecules L' to give complexes Rh(PiPr3)2ClL'. The enthalpy of this reaction has been determined calorimetrically and/or by equilibrium methods for L' = N2, C2H4, diphenylacetylene, and 2-butyne. These values, in combination with the previously determined lower limit for the [Rh(PiPr3)2Cl]2 bridge strength, afford lower limits of the Rh-L BDE's; the lower limits are probably only slightly less than the actual BDE's.
