Two novel diphoshinoamine ligands have been synthesized. Combination of Cr(Ⅲ) and methylaluminoxane(MAO) generated active catalytic system which can catalyze tetramerization of ethylene with high catalytic activity up to 2.5×10^-6g/mol Cr.h and high selectivity to produce 1-octene (C₈ in products is being 89.80 wt%).
