稀土烯丙基化合物的研究(Ⅲ)——镝、钬和铒的烯丙基化合物的合成

STUDIES ON RARE EARTH-ALLYL COMPOUNDS (III)——SYNTHESIS OF ALLYL COMPOUNDS OF Dy, Ho AND Er

由无水稀土氯化物与烯丙基锂在四氢呋喃-乙醚中反应,合成了三个新的对空气极敏感的稀土烯丙基化合物.经元素分析、红外光谱鉴定等确定其组成为Li_2Ln(C_3H_5)_5·2.5 Dioxane(Ln=Dy、Ho、Er).

Three new rare earth-allyl compounds, which are very sensitive to air and moisture, have been synthesized by the reaction of anhydrous lanthanide trichloride with allyllithium in THF-ether solution. Their general formula Li_2Ln(C_3H_5)_5·n Dioxane (Ln=Dy, Ho, Er;n=2.5) were proved by elemental analyses and infrared pectra.
