Abstract
The chiral five-coordinate halide compound, Salcen(tBu)AlCl (1) (Salcen = N,N′-cyclohexylenebis(3, 5-di-tert-butylsalicylideneimine) can be used in a salt elimination reaction to produce [R,R'Salcen(tBu)AlOTs] (2) as well as the chiral cationic complex, [R,R'Salcen (tBu)Al(thf)2]+ BPh4 − (3). The conditions under which these types of neutral and cationic complexes form will be discussed. This should provide guidance for the eventual use of the cations as strongly Lewis acidic catalysts and organic synthetic reagents.
