Abstract

A new dealkylation reaction between organophosphate esters and Salen aluminum bromide compounds has been used to prepare three new aluminum salen compounds salen(tBu)AlOP(O)Ph2 (1) (salen = N,N′-ethylenebis(3,5-di-tert-butylsalicylideneimine)), [(MeOH)Alsalen(tBu){OMePO2(O)}Alsalen(tBu) {OMePO2(O)}Alsalen(tBu)]Br (2). and [salpen( tBu)AlO]2[(BuO)2PO]2 (3) (salpen = N,N′-propylenebis(3,5-di-tert-butylsalicylideneimine)). Compounds 1-MeOH, 2, and 3 were characterized by single-crystal X-ray diffraction. Compound 1 is the first example of a monomeric aluminum Schiff base phosphinate. Compound 2 is a cationic Salen aluminum phosphate, and compound 3 contains an aluminophosphate ring. This work is the first example of the intentional use of an aluminum-based dealkylation reaction to form new compounds.
