    • In the case of exchange between alkenes in α-diimine derivatives of Pd(O) a value of ΔH0, 3.5 ±0.5 kcal mol -1 was determined.11 From that value under the reasonable hypothesis that the slope of the Van't Hoff relationship does not change considerably on going from the exchange between two alkenes to the exchange of an alkene with an alkyne, the value of KE298K was calculated from the expression In KE298K, In KE213K-(ΔH 0/R)(213-298, 213 × 298, KE ≈ 66. We consider that approach reliable since we have also studied the RT exchange between maleic anhydride and dmdb in pyridylthioether derivatives of Pd(0)9g and the exchange constant between [Pd(η2-fn)neoc, and dmbd. 14 The equilibrium constants determined in those cases when multiplied by 7900 and 4400 give the values of 110 and 54, respectively, which compare quite we
