80年代初Schumann首先报道了稀土金属有机氢化物的合成研究。由于稀土金属有机氢化物具有超高的催化活性及潜在的应用可能性,因而获得了迅速的发展。现在已成为稀土有机化学的研究热点。由于稀土有机氢化物对空气和湿气极端敏感,这给它的合成、分离和鉴定带来很大的困难。我们曾 Schumann first reported the synthesis of rare earth metal hydride in the early 1980s. Due to its high catalytic activity and potential application possibilities, rare earth metal hydride has gained rapid development. Now it has become a hot research field of rare earth organic chemistry. Due to the extreme sensitivity of rare earth organic hydrides to air and moisture, this poses great difficulties for its synthesis, separation and identification. We have
