Abstract

The present work entails the synthesis and first structural characterization of complexes possessing a single Al-O-Si linkage. These are of the formula LAlOSiPh₃ (L = Salen(^tBu) (N,N′-ethylenebis(3, 5-di-tert-butylsalicylideneimine)) (11); Salpen(^tBu) N,N′-propylenebis(3,5-di-tert-butylsalicylideneimine)) (12); Salophen(^tBu) (N,N′-phenylenebis(3,5-di-tert-butylsalicylideneimine)) (13); and Salomphen(^tBu) (N,N′-(3,4-dimethylphenylene)bis(3,5-di-tert-butylsalicylideneimine)) (14). They are formed by combining the novel five-coordinate aluminum alkyl starting materials L(^tBu)AIR (where L = Salen(^tBu), R = Me (1), Et (2), ⁱBu (3); Salpen(^tBu), R = Me (4), Salophen(^tBu) R = Me (5), Et (6), ⁱBu (7); and Salomphen, R = Me (8), Et (9), ⁱBu (10)) with Ph₃SiOH in toluene. All of the compounds were characterized spectroscopically and, in the case of 1, 10, 11, 12, and 13, by X-ray crystallography.
