稀土金属有机化合物的合成和研究已经取得了很大进展,特别是一系列σ键化合物的合成开辟了金属有机化学的新领域。对稀土金属有机化合物的研究既具有重要的理论意义,也有很大的实际意义。稀土金属有机化合物的发展基于二茂铁[Fe(C_5H_5)_2]的合成。三十年代后期的PIetz和四十年代中期的Gilman和Jones,他们就试图合成ⅢB族元素金属有机化合物,结果没有成功。五十年代中期的Wilkinson和Birmingham首先合成了稀土金属三环戊二烯化合物。到六十年代已能合成出一系列稀土金属环戊二烯化合物。稀土金属有机化合物在八十年代的今天仍是一个非常活跃的学科领域。稀土金属有机化合物可按其相连基团(或配位基)的类型来分类;也可以按稀土金属与配位体之间键的类型来分
Great progress has been made in the synthesis and research of rare earth metal organic compounds. In particular, the synthesis of a series of sigma bond compounds opens up new fields in metalorganic chemistry. The study of rare earth metal organic compounds not only has important theoretical significance, but also has great practical significance. The development of rare earth metal organic compounds is based on the synthesis of ferrocene [Fe (C_5H_5) _2]. In the late 1930s, PIetz and Gilman and Jones in the mid-1940s, they tried to synthesize Group IIB metal-organic compounds without success. In the mid-1950s, Wilkinson and Birmingham first synthesized rare-earth tricyclopentadiene compounds. By the 1960s, a series of rare earth metal cyclopentadienyl compounds had been synthesized. Rare earth metal organic compounds in the 1980s is still a very active subject area. Rare earth metal organic compounds according to the type of their associated groups (or ligands) to the classification; rare earth metals and ligands can also be divided according to the type of bond
