posted on 15.05.2006, 00:00 authored by Amitabha Mitra, Sean Parkin, David A. AtwoodA 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.
