um and (8-methoxynaphthyl)lithium, yielding bis(2-methoxybenzyl)methylaluminum (8), bis(8-methoxynaphthyl)methylaluminum (11), and bis(8-methoxynaphthyl)ethylaluminum (12), respectively. The new compounds have been characterized by elemental analysis, NMR spectroscopy, and mass spectrometry. The solid-state structures of 6, 8, 9, and 11−13 were determined by single-crystal X-ray diffraction. The new
烯丙基醚CH 2 CHCH 2 OR与i的氢铝化卜2的AlH产生了(3-烷氧基丙基)二异丁基铝络合物我Bu 2 Al(CH 2)3 OR(R = Me(1),Et(2),Bu(3))。Et 2 AlCl和iBu 2 AlCl与(2-(甲氧基甲基)苯基)锂和(2-甲氧基苄基)氯化镁反应,生成(2-(甲氧基甲基)苯基)二乙基铝(4),(2-(甲氧基甲基)苯基)二异丁基铝(5),和(2-甲氧基苄基)二异丁基铝(7)。我的反应Bu 2 AlCl与(2-甲氧基苯基)锂一起得到二聚双((2-甲氧基苯基)二异丁基铝)(6)。等2的AlCl和(8-乙氧基萘)锂形式(8-乙氧基萘)二乙基铝(10)与二氯化(8-乙氧基萘)铝(几晶体沿13)。AlCl 3与2当量的(2-甲氧基苄基)氯化镁反应,得到双(2-甲氧基苄基)氯化铝(9)。Me 2 AlCl和Et 2 AlCl与(2-甲氧基苄基)镁和(8-甲氧基萘基)
