过渡金属配合物在均相催化中已得到广泛的应用,通过对催化作用中的一些基本反应如配体取代、氧化加成、插入反应等动力学和机理的研究,从中找出一般规律,不论在理论上和实际上都有着重要的意义。一系列研究表明,低氧化态过渡金属配合物如η~5-C_5H_5M(CO)_2与配体交换速率的次序为:CoIr,CrW,NiPt,即第二列过渡金属配合物在同一族中反应最快,因此常常选
Transition metal complexes have been widely used in homogeneous catalysis. The general rules of the transition metal complexes are found through some basic reactions in catalysis, such as ligand substitution, oxidation addition, insertion reaction and other mechanisms. In theory and in fact have important significance. A series of studies have shown that the order of the exchange rates of low-oxidation transition metal complexes such as η5-C_5H_5M (CO) _2 and ligand is Co Ir, Cr W, Ni Pt, The second column of transition metal complexes in the same family in the fastest response, it is often elected
