Abstract:	取一倍量的Li{C4H2N(CH2NMe2)2-2,5}或者是二倍量的Li{C4H3N(CH2NMe2)-2}與氯化鋁在-78 ℃ ，以乙醚為溶劑的情況下可生成 AlCl2{C4H2N(CH2NMe2)2-2,5} 【1 】及 AlCl{C4H3N(CH2NMe2)-2}2【2】此二種錯化合物。將化合物1 在乙醚中用甲基鋰進行烷基化反應，則可生成二甲基鋁錯化合物3。化合物2 熱不穩定，在CHCl3 中加熱至80℃二天後，會變成未知的化合物。化合物1,2,3均有完整的NMR光譜圖以及X-ray 的結構測定。 Reactions of AlCl3 with one equiv of Li{C4H2N(CH2NMe2)2-2,5} or two equiv of Li{C4H3N(CH2NMe2)-2} in diethyl ether at –78 °C afforded AlCl2{C4H2N(CH2NMe2)2-2,5} 1 and AlCl{C4H3N(CH2NMe2)-2 } 2, respectively. Alkylation of 1 with MeLi in diethyl ether generates the aluminum dimethyl complex 3. Compound 2 is thermally unstable and was converted to uncharacterized product in CHCl3 within two days at 80 °C. Compounds 1, 2, and 3 were characterized by NMR spectroscopy and X-ray structure determination. Keywords: aluminum, pyrrole, Alkylation
