Stereochemical control of cis- and trans-TiCl2 groups in six-coordinate complexes [(L)TiCl2] (L2− = N2O2-donor Schiff base) and reactions with trimethylaluminium to form cationic aluminium species

The first example of a cis-configuration of the TiCl2 group in a six-coordinate titanium complex [(L)TiCl2], involving a tetradentate N2O2-donor Schiff base ligand (L2–), is reported, and reactions of such complexes with trimethyl aluminium have been shown to generate cationic aluminium species.
