Abstract
A series of amino-salicylaldimine ligands, 5-tert-butyl-3-(R-1-ylmethyl)-salicylaldimine (L1-4, R = morpholine, piperidine, pyrrolidine, 4-methylpiperazine) have been synthesised and structurally analysed. The molecular structure of compound (L1, R = piperidine) has been determined by single-crystal X-ray diffraction. These ligands reacted with [CrCl3(THF)3] in THF to form chromium complexes, which were isolated in high yields as stable green solids and characterised by means of IR and elemental analysis. Activated with methylaluminoxane (MAO), these complexes showed moderate catalytic activities for ethylene oligomerisaton.
