摘要：

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(Bu-t) (N,N'-ethylenebis(3, 5-di-tert-butylsalicylideneimine)) (11); Salpen(Bu-t) N,N'-propylenebis(3,5-di-tert-butylsalicylideneimine)) (12); Salophen(Bu-t) (N,N'-phenylenebis(3,5-di-tert-butylsalicylideneimine)) (13); and Salomphen(Bu-t) (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(Bu-t)AIR (where L = Salen(Bu-t), R = Me (1), Et (2), Bu-i (3); Salpen(Bu-t), R = Me (4), Salophen(tBu)R = Me (5), Et (6), Bu-i (7); and Salomphen, R = Me (8), Et (9), Bu-i (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.
