近年来稀土金属有机化合物的合成及研究已经取得了很大的进展.新的合成方法,新类型的化合物,以及稀土金属有机化合物在高分子催化及有机合成中的应用越来越引起人们的广泛兴趣.稀土金属有机化合物的一般合成方法,主要采用稀土无水氯化物与各种碱金属有机化合物(烷基,芳基、炔基等)进行反应.只有少数稀土金属(E_u,Yb),由于能够溶于液态氨中,可直接同有机物反应而得到金属有机化合物.但在最近几年,人的采用热原子蒸汽法以及稀土金属同有机碘和有机汞化合物反应的方法进行了许多工作,使稀土金属有机化合物的合成展现出新的局面.本文对于从零价稀土合成稀土金属有机化合物的各种方法简单做出分类讨论.
In recent years, great progress has been made in the synthesis and research of rare earth metal organic compounds. New synthesis methods, new types of compounds, and the application of rare earth metal organic compounds in polymer catalysis and organic synthesis are attracting more and more people Interests General synthesis of rare earth metal organic compounds, the main use of rare earth anhydrous chloride and various alkali organic compounds (alkyl, aryl, alkynyl, etc.) reaction. Only a few rare earth metals (E_u, Yb), due to Able to dissolve in liquid ammonia and react directly with organic compounds to produce organometallics, but in recent years there has been much work carried out by methods of thermal atom steaming and the reaction of rare earth metals with organic iodine and organic mercury compounds. The synthesis of rare earth metal organic compounds shows a new situation.In this paper, we discuss the various methods for synthesizing rare earth metal organic compounds from zero-valent rare earths.
