氧原子转移试剂存在下金属羰基化合物ＣＯ取代反应动力学的系统研究表明，反应速率对金属羰基化合物、氧原子转移试剂和进入试剂的浓度分别为一级、一级和零级。这表明反应可能为缔合机理，过程涉及转移试剂氧原子在羰碳原子上发生亲核进攻，生成一个良好离去基团ＣＯ２的同时产生了一个活性中间体，后者与进入试剂发生快反应得产物。从金属羰基化合物和氧原子转移试剂两个方面讨论了影响ＣＯ取代反应速率的各种因素。 A systematic study on the kinetics of CO substitution reaction of metal carbonyls in the presence of an oxygen atom transfer reagent showed that the reaction rates were first order, first order and zero order for the concentration of metal carbonyls, oxygen atom transfer reagents and reagents. This suggests that the reaction may be an associative mechanism involving the transfer of the nucleophilic attack of the oxygen atom of the reagent on the carbonyl carbon to produce a good leaving group CO2 while producing an active intermediate which reacts rapidly with the entering reagent The product. The factors affecting the rate of CO substitution reaction are discussed from two aspects of metal carbonyl and oxygen atom transfer reagent.
