A new P-N-P ligand having the general formula (Ph1)(Ph2)P-N-P1CPh3)(Ph4) R2 wherein each of Ph1, Ph2, Ph3 and Ph4 is a phenyl group bonded to a phosphorus group, and R2 is selected from the group consisting of hydrogen, C1-20 hydrocarbyl and silyl, is useful in ethylene tetramerization Pn combination with i) a source of chromium and 11) an activator such as methylalumoxane, the ligand of this invention may be used to prepare an oligomer product that contains a mixture of hexenes and octenes When produced under preferred reaction conditions, the hexenes and octenes produced with this ligand contain very low levels of internal olefins.
具有一般式(Ph1)(Ph2)P-N-P1CPh3)(Ph4)R2的新P-N-P配体,在其中Ph1、Ph2、Ph3和Ph4中的每一个都是键合到磷的苯基,R2从氢、C1-20烃基和硅基中选择,用于与i)铬源和ii)活化剂(如甲基铝氧化物)结合在一起对乙烯四聚反应中有用。本发明的配体可用于制备含有己烯和辛烯混合物的寡聚体产品。在优选反应条件下生产时,使用该配体产生的己烯和辛烯含有非常低水平的内烯烃。
