文摘
Two ligands [ortho-C6H4NR2(CH2NH)]2CH2CH2(3: R=Me; 4: R=Et) were prepared by the reduction of preligands [ortho-C6H4NR2(CH=N)]2CH2CH2(1: R=Me; 2: R=Et). These ligands reacted with AlMe3 to afford the corresponding dinuclear aluminum complexes {AlMe2[ortho-C6H4NR2(CH2N)]}2CH2CH2(5: R=Me; 6: R=Et). All the compounds were characterized by 1H and 13C nuclear magnetic resonance(NMR) spectroscopies and elemental analyses. The catalytic properties of the aluminum complexes towards the ring-opening polymerization of lactones were investigated in the presence of benzyl alcohol. All the polymerization reactions were proceeded in a controlled manner.
