Abstract A series of Al(III) unsymmetrical β-aminoalcohol based complexes 1–6 were synthesized via metalation of the corresponding ligands 1′–6′ those were prepared by the reaction of benzylamine with readily available epoxides viz., styrene oxide, 1,2-epoxy-3-phenoxypropane, 4-tertbutylphenyl glycidyl ether, 4-chlorophenyl glycidyl ether, glycidyl 2-methylphenyl ether and 1,2-epoxyhexane. Among these
摘要 通过相应配体 1'-6' 的金属化合成一系列 Al(III) 不对称 β-氨基醇基配合物 1-6,这些配合物是通过苄胺与容易获得的环氧化物即氧化苯乙烯 1 反应制备的。 2-环氧-3-苯氧基丙烷、4-叔丁基苯基缩水甘油醚、4-氯苯基缩水甘油醚、2-甲基苯基缩水甘油醚和1,2-环氧己烷。在这些配合物中,发现配合物2在常压下芳氧基/脂肪族末端环氧化物与CO 2 的环加成反应中最有效,得到相应的环状碳酸酯,在四丁基铵存在下具有高转化率和选择性(高达>99%)。溴化物作为助催化剂。
