The intramolecularly base-stabilized arylaluminum dihydride [2,6-(Me2NCH2)2C6H3]AlH2 (1) has been prepared by the metathesis reaction of the corresponding lithium aryl with AlH2Cl·NMe3. Alternative methods for the synthesis of 1 are transmetalation or reduction reactions of [2,6-(Me2NCH2)2C6H3]MCl2 (M = Al (2), Ga (3), In (4)) with LiAlH4. The x-ray crystal structures of 1 and 2 have been determined:
通过相应的芳基锂与AlH 2 Cl·NMe 3的复分解反应,制备了分子内碱稳定的芳基二氢化铝[2,6-(Me 2 NCH 2)2 C 6 H 3 ] AlH 2(1)。合成1的替代方法是[2,6-(Me 2 NCH 2)2 C 6 H 3 ] MCl 2(M = Al(2),Ga(3),In(4))的金属转移或还原反应与LiAlH 4。已经确定了1和2的X射线晶体结构:1,正交,Pbca,具有;2,单斜,,用。化合物1和2为固态单体。
