AluminiumkomplexeSchiffscher Basen@@@Al(III) complexes with Schiff bases
1977
Reactions of Aluminium isopropoxide with monofunctional bidentateSchiff bases, such as salicylidene-o-toluidine, salicylidene-p-toluidine, 2-hydroxy-1-naphthylmethylidene-p-toluidine and 2-hydroxy-1-naphthylmethylidene-p-toluidine in different stoichiometric ratios have yielded products of the type Al(OPr
i)2(SB), Al(OPr
i)(SB)2, and Al(SB)3 (whereSB
− is the anion of the correspondingSchiff base,SBH). Bifunctional tetradentateSchiff bases in 1∶1 and 2∶3 molar ratios [Al(OPr
i)3:SBH2] yielded insoluble derivatives of the type Al(OPr
i)SB and Al2(SB)3 (whereSB
− represents the anion of theSchiff baseSBH2 andSBH2=bis-salicylaldehyde-o-phenylene-diamine or bis-salicylaldehyde-p-phenylenediamine). The newSchiff base derivatives have been characterized by elemental analyses, infrared spectroscopy and molecular weight determinations.
