金属有机氢化物是计量和催化反应的重要中间体。自1981年Evans首次合成并鉴定了稀土有机氢化物以来,对它的研究工作得到了相当快的发展。近年来,相继报道了几种稀土有机氢化物的合成方法,并研究了它们的化学性质。研究结果表明,稀土有机氢化 Metallic organic hydride is an important intermediate for the measurement and catalytic reactions. Since its first synthesis and identification of rare earth organic hydrides in 1981, Evans has achieved a fairly rapid development of its research work. In recent years, several methods of synthesizing rare earth organic hydrides have been reported one after another, and their chemical properties have been studied. The results show that rare earth organic hydrogenation
