摘要：

Alkenes (cyclohexene; 1-octene) and dienes (cyclooctadiene, COD; norbornadiene, N13D) react with CiS-PtCl2(CO)2, leading, respectively, to partial and complete displacement of coordinated carbon monoxide. Equilibrium constants at 21 degrees C in 1,2-dichloroethane are (2.4 +/- 0.5) x 10(-3) and (2.8 +/- 0.4) x 10(-2) for cyclohexene and 1-octene, respectively. Thermodynamic data correspond to Delta H degrees (kJ mol(-)) and Delta S degrees (J mol(-1) K-1) = 30 +/- 4 and 51 +/- 15 for cyclohexene and 36 +/- 2 and 95 +/- 8 for 1-octene.
