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
