1951年报导了第一个过渡金属的茂金属化合物二茂铁。二茂铁的发现,引起了对大量过渡元素茂金属化合物的合成。结构和反应性能的研究,目前已制出许多茂金属化合物,且迅速发展,从而开辟了一个新的化学领域——茂金属化学(metallocenechemistry)。 茂金属是以环戊二烯基(称为茂)为有机配体与金属键合的一类化合物。表—1列举了一些重要的茂金属化合物。茂金属根据键合情况可分为三类:离子型结构茂金属; 1951 reported the first transition metal metallocene compound ferrocene. The discovery of ferrocene has led to the synthesis of a large number of transitional element metallocene compounds. Structure and reactivity, many metallocene compounds have been made and developed rapidly, thus opening up a new chemical field, metallocene chemistry. Metallocenes are a class of compounds that are bonded to metals with cyclopentadienyl groups (referred to as metallocenes) as organic ligands. Table-1 lists some important metallocene compounds. Metallocene can be divided into three categories according to bonding conditions: ionic structure metallocene;
