化学这门学科以往曾仔细加以分类,认为除了物理化学外,可分成无机化学和有机化学二大类,但是,最近二十年来,由于无机化学和有机化学的相结合,出现了第三类化学,即有机金属化学。它的飞速发展,已成为当前最活跃的化学领域之一。在有机化学教科书中详细介绍的Grignard试剂,是非常有用的反应试剂,而它本身就是烷基和镁相结合的有机金属化合物。Reformatsky反应中的反应试剂就是BrZnCH_2COOR这一有机锌化合物。具有齐聚结构的烷基锂既是阴离子聚合的催化剂,又是有机合成中有用的试剂。早已众所周知的以Sandmeyer,Gattermann,Ullmann,等人命名的反应一向看作是应用铜催化剂的反应,现在则可看作是有机铜化合物的反应。有机金属化学之所以迅速发展,是以二茂铁结构之阐明,及Ziegler-Natta催化剂之发 The discipline of chemistry has been carefully classified in the past, and considered besides physical chemistry, it can be divided into two categories: inorganic chemistry and organic chemistry. However, in the recent two decades, due to the combination of inorganic chemistry and organic chemistry, the third chemistry , That is, organometallic chemistry. Its rapid development has become one of the most active chemical fields at present. The Grignard reagent, described in detail in organic chemistry textbooks, is a very useful reagent and is itself an organometallic compound combining alkyl and magnesium. Reformatsky reaction reagent is BrZnCH_2COOR this organozinc compound. The alkyllithium with oligomeric structure is both an anionic polymerization catalyst and a useful reagent in organic synthesis. The reaction, already well-known by Sandmeyer, Gattermann, Ullmann, et al., Has always been regarded as a reaction using copper catalysts and now can be seen as a reaction of organocopper compounds. The rapid development of organometallic chemistry, is the elucidation of the structure of ferrocene, and Ziegler-Natta catalyst
