An unusual imine (NC) alkylalumination reaction

Abstract

Addition of 3 equiv. of AlMe ₃ to a heptadentate Schiff-base ligand made from salicylaldehyde and bis(2-aminoethyl)- ethylenediamine (H ₃ L ¹ ) results in an unusual alkylalumination of one of the imine bonds; addition of 2 equiv. of B(OMe) ₃ or AlMe ₃ to one of these ligands leads to the formation of bimetallic derivatives containing four- and five-coordinate metals, respectively.
