本文研究了在苯和二甲基甲酰胺中下列系列反应的动力学：f/ww-IrX（CO）（PPh_3）_2 + YZ-*· IrXYZ（CO）（PPh_3）_2，其中X=Cl，Br，I，YZ= H_2，O_2，CH_3。在每种情况下，动力学被发现服从二级速率定律，速率= ε 2 [IrX（CO）（PPh 3）2][YZ]。与H2和O2的反应的动力学模式非常相似。在苯中，这些反应的活化参数均在AH*= 10.8至13.1千卡/摩尔和AS*=-14至-24欧的范围内。在每种情况下，
A study is described of the kinetics of the following series of reactions in benzene and dimethylform-amide, f/ww-IrX (CO)(PPh3) 2+ YZ-*· IrXYZ (C0)(PPh3) 2, where X=Cl, Br, and I and YZ= H2, 02, and CHal. The kinetics, in each case, were found toobey the second-order rate law, rate=£ 2 [IrX (CO)(PPh3) 2][YZ]. The kinetic patterns of the reactions with H2 and 02 were very similar. The activation parameters for these reactions, in benzene, were all in the range AH*= 10.8 to 13.1 kcal/mole and AS*=—14 to—24 eu. In each case the de-
