摘要：
A series of novel asymmetric bidentate phosphines with ortho-fluorine substituents was developed and characterized. In combination with chromium, the compound gave high activity to 1-hexene and 1-octene (approaching 3200 kg/g Cr/h) and high combined selectivity (C-5-C-8 > 95% in selected examples). With fluorine atoms at the ortho-position, the compound could be operable at a higher temperature without activity loss.
