苯、萘以及各种芳香杂环的多官能化衍生物是聚合物、药物、香料、染料、炸药、杀虫剂等的重要中间体 ,从相应的卤代芳烃出发合成这些化合物是经济和合理的 .但由于卤代芳烃对亲核取代的不活泼性 ,使这一设想受到很大的限制 .近年来 ,金属有机化学的发展 ,给卤代芳烃的化学带来 Benzene, naphthalene and polyfunctional derivatives of various aromatic heterocycles are important intermediates for polymers, drugs, perfumes, dyes, explosives, insecticides and the like. It is economical and reasonable to synthesize these compounds from the corresponding halogenated aromatic hydrocarbons However, due to the inactivation of halogenated aromatic nucleophiles, this idea has been greatly restricted in recent years, the development of metal organic chemistry, the chemical brought to halogenated aromatic hydrocarbons
