金属羰基化合物取代反应动力学和机理的研究是从五十年代末期开始的。可溶性过渡金属配合物催化剂在一系列反应中日益广泛的应用,促使该领域的研究在近十多年内变得很活跃,不仅涉及单核羰基化合物,而且深入到金属羰基簇化物。低价的配位不饱和中心金属原子上配位体取代反应的研究,是阐明均相催化过程以及设计新催化剂所必不可少的基础工作。本文目的在于:通过典型实例,介绍这类研究能够提供哪些有价值的信息。论述范围仅限于单核羰基化合物,有兴趣了解更多情况的读者可参阅有关综述及其所引用的文献资料。
The study of metal carbonyl substitution kinetics and mechanism began in the late 1950s. The increasing use of soluble transition metal complex catalysts in a series of reactions has prompted research in this area to become active over the last ten years, involving not only mononuclear carbonyls but also metal carbonyls. The research on the substitution reaction of the ligands on the metal atom with a cheap coordination center is essential to clarify the homogeneous catalysis process and to design a new catalyst. The purpose of this article is to: Describe, through typical examples, what valuable information such research can provide. The discussion is limited to mononuclear carbonyls and readers interested in learning more can refer to the review and the literature cited.
