Probing the redox chemistry of β-diketiminate supported aluminium complexes

Abstract

A combined electrochemical and synthetic investigation was undertaken to probe aluminium's redox capabilities. Reduction from Al(III) to Al(I) occurs in a stepwise manner via Al(II). The highly reactive Al(I) species induces a catalytic electrochemical-chemical (EC′) reaction, however, reversible redox processes are observed in the individual steps [Al(III)↔Al(II) and Al(II)↔Al(I)].
