Abstract
Treatment of CrCl3(THF)(3) with the lithium and sodium salts of the reduced Schiff-base ligand 3,5-(Bu-t)(2)-2-(OH)C6H2CH2NH(2,6-Me2C6H3) affords bis- chelate chromium(II) and mono-chelate chromium(III) complexes respectively; both give active ethylene polymerisation catalysts upon treatment with alk ylaluminium activators.
