Abstract

The combination of one and two equivalents of AlMe₃ with the ligand, Salean(^tBu)H₄ (N,N′-bis((3,5-di-tert-butyl)-2-hydroxybenzyl)-1,2-diamino ethane) leads to the compounds, Salean(^tBu)H₂AlMe (1), and Salean(^tBu)HAlMe(AlMe₂) (2). When 2 is exposed to air, [Salean(^tBu)HAlOMe]₂ (3) first forms, and then, after several days, [Salean(^tBu)H₂AlOH]₂ (4). Compound 4 is the only product that occurs when 1 is exposed to air. All four compounds have been characterized by spectroscopic (IR, ¹H NMR, ²⁷Al NMR) and physical techniques (Mp, C,H analysis) and, in the case of 3 and 4, by X-ray crystallography. The structures consist of dimeric units with bridging OMe and OH groups.
