Research progress of catalysts for ethylene selective tetramerization to1-octene

Ligand structure， which include biphosphine amine ， ethyl bridged biphosphine and carbon-nitrogen bridged phosphine amineligands， together with co-catalyst and reaction mechanism of chromium complexes had been used to analyze recent research progress in the field of selective tetramerization of ethylene with 22 references. The transition metal chromium complex had been found excellent catalytic activity and product specificity in selective oligomerization of ethylene， and was studied as the principal catalyst for the synthesis of linear-olefins such as 1-hexene and 1-octene， according to reports. The ligand structure was found to be a key factor that affecting the structure of the chromium complexes and the performance of the catalytical active center.
