稀土烯丙基化合物的研究(VII)——镧、铈、镨、钕和钐的2-甲基烯丙基化合物的合成

STUDIES ON RARE EARTH-ALLYL COMPOUNDS(Ⅶ)——THE SYNTHESIS OF METHALLYL COMPOUNDS OF

用无水稀土氯化物与2-甲基烯丙基氯化镁及四甲基乙二胺(tmed),在四氢呋喃中反应,合成了五个对空气和湿气相当敏感的轻稀土元素2-甲基烯丙基化合物Ln(C_4H_7)_2Cl_5Mg_2(tmed)_2[Ln=La,Ce,Pr,Nd和Sm].化合物均经元素分析、红外光谱及质谱的鉴定,并进行了摩尔电导的测定.

Five new methallyl lanthanide compounds (C_4H_7)_2LnCl_5Mg_2(tmed)_2(Ln=La, Ce, Pr, Nd, and Sm) have been prepared by the reaction of anhydrous LnCl_8 with methallylmagnesium chloride and tetramethylenediamine (tmed) in THF at O C. The Compounds are sensitive to air and moisture. The Compounds have been characterized by elemental analyses, infrared spectra and mass spectra.
