In the present manuscript we will detail the first use of the Salen(tBu)H2 ligands with the group 13 elements. This includes the compounds of formula Salen(tBu)AlCl (where Salen = Salen(N,N′-ethylenebis(3,5-di-tert-butylsalicylideneimine)) (1), Salpen (N,N′-propylenebis-(3,5-di-tert-butylsalicylideneimine)) (2), Salophen CZV7ST-benzenylidenebis(3,5-di-ieri-butyl-salicylideneamine)) (3), and Salomphen (N,N′-(3,4-dimethylbenzenylidene)bis(3,5-di-tert-butylsalicylideneimine)) (4)) and the novel five-coordinate monomeric amides of formula LAINRR′ (where L = Acen (N,N′-ethylenebis((tBu)salicylidene(nethyl)imine); R, R′ = H, Ph (5); R = R′ = SiMe3 (6)) and L = Salen (R, R′ = H, tBu (7), H, Ph (8), and H, Dipp (2,6-diisopropylphenyl) (9); R = R′ = Me (10), Et (11), and SiMe3 (12))). Additionally the unique monomeric hydroxy complex Salen(tBu)AlOH (13) and its condensation product, (Salen(t-Bu)Al)2O (14), will be described. All of the compounds were characterized by spectroscopic (1H, 13C, and 27Al NMR, IR) and physical (mp, analyses) techniques. X-ray crystallographic data are presented for 14.
