摘要

The reactions of the charge neutral dinuclear aluminum tetraalkyl complexes of di-Schiff base ligands, i.e. AlMe2{ON}-R-{ON}AlMe2 (1a, R = 1,3-propylene; 1b, R = 1,3-cyclohexylene) with B(C6F5)(3) and H(Et2O)(2)(+)H2N{B(C6F5)(3)}(2)(-) were investigated. When B(C6F5)(3) was used as the cationizing agent (1 or 2 equiv. vs. Al), only monocationic dinuclear complexes 2a,b(+)MeB(C6F5)(3)(-) were obtained. In contrast, with H(Et2O)(2)(+)H2N{B(C6F5)(3)}(2)(-), both mixed-dicationic 3a,b center dot(OEt2)(2)(2+)MeB(C6F5)(3)(-)H2N{B(C6F5)(3)}(2)(-) and homo-dicationic 3a,b center dot(OEt2)(2)(2+)H2N{B(C6F5)(3)}(2)(2)(-) ion-pairs were prepared. All cationic complexes were characterized by H-1, C-13, F-19 and B-11 NMR spectroscopy, and an X-ray diffraction study was performed for 3b center dot(OEt2)(2)(2+)H2N{B(C6F5)(3)}(2)(2)(-).
