| 摘 要： | 本文研究了在Me_3NO存在下Ru_3(CO)_(11)L(L_=PPh_3,PBu_3~n)的CO取代反应动力学,并提出了可能的机理。Ru_3(CO)_(11)L中的CO被配体L取代生成Ru_3(CO)_9L_3。当L=PPh_3,r=(k_1 k_2Me_3NO])Ru_3(CO)_(11)L];L=PBu_3~n,r=(k_1 k_2PBu_3~n])Ru_3(CO)_(11)L].除了涉及简单的离解机理外,还存在着按缔合机理进行的简单CO热取代与Me_3NO对Ru_3(CO)_(11)L中羰基碳的进攻。

| Abstract: | CO substitution reaction of Ru3(CO)11L (L = PPh3and PBu3n) with additional L forms Ru3(CO)9L3, The reaction follows a two-term rate law: r=(k1 k2Me3NO])Ru3(CO)11L], (L = PPh3); r=(k1 k2PBu3n])Ru3(CO)11L], (L = PBu3).A mechanism is proposed which involves a competition between the attack of Me3NO on carbonyl carbon and the attack of L on Ru atom besides via a simple dissociative path. |
