Abstract
The bimetallic compounds, L(AlMeCl)2 with L = Salpen(tBu) (N,N'-1,3-propylenenebis(3,5-di-tert-butylsalicylideneimine), Salben(tBu) (N,N'-1,4-butylenebis(3,5-di-tert-butylsalicylideneimine)) and Salhen(tBu) (N,N'-1,6 hexylenebis(3,5-di-tert-butylsalicylideneimine)) form the unusual trimetallic dicationic complexes, {[Salpen((t)Bu)*]2(AlCl)3]}2+[GaCl4]- [GaMe2Cl2]- (1), {[Salben((t)Bu)*]2(AlCl)3]}2+[GaCl4]-[GaMe2Cl2]- (2) and {[Salhen((t)Bu)*]2(AlCl)3]}2+[GaCl4]- [GaMe2Cl2]- (3) when combined with GaCl3 in toluene. In their formation, the ligands of the compounds undergo a unique dealkylation reaction to lose one tBu group from each ligand (marked with an asterisk). These compounds are a new and unique class of aluminum cations. The compounds were characterized by Mp, analyses, IR, 1H NMR, and in the case of 1 and 2, by single-crystal X-ray diffractometry.
