The invention relates to a process for producing a complex for use in olefin polymerization and oligomerization of the general formula (III):
wherein Mt is a group 3 to 12 element in a +2 to +6 oxidation state with between 1 to 4 additional ligands (anionic and/or neutral) coordinated, wherein R1 and R2 are hydrogen, halogen, alkoxy, or a hydrocarbon group containing between 1 to 12 carbon atoms; E is a group 16 element, preferably O; Z is a direct bond between carbon atoms of the adjacent aromatic rings or a —CR3R4— or —SiR3R4— bridge between those carbon atoms, where R3 and R4 are hydrogen or a hydrocarbon groups with 1 to 10 carbons, R5, R6, R7 and R8 are hydrogen, halogen, alkoxy, or a hydrocarbon group containing between 1 to 10 carbon atoms and J1 and J2 are —NR9R10 or —PR9R10, where R9 is H or SiMe3 group and R10 is selected from a group consisting of alkyl, aryl, substituted aryl, heteroalkyl, and heteroaryl containing between 1 to 30 non-hydrogen atoms through a route involving novel precursors such as compounds represented by the general formula (I)
where the various substitution options are adapted to produce the substituents shown for formula (III) above.
本发明涉及一种用于制备用于烯烃聚合和寡聚的复合物的方法,其通式为(III):其中Mt是+2至+6氧化态的3至12族元素,带有1至4个额外配体(阴离子和/或中性),其中R1和R2是氢、卤素、烷氧基或含有1至12个碳原子的碳氢基;E是16族元素,优选为氧;Z是相邻芳香环的碳原子之间的直接键或-CR3R4-或-SiR3R4-桥,其中R3和R4是氢或含有1至10个碳原子的碳氢基,R5、R6、R7和R8是氢、卤素、烷氧基或含有1至10个碳原子的碳氢基,J1和J2是-NR9R10或-PR9R10,其中R9是H或SiMe3基,R10选自包含1至30个非氢原子的烷基、芳基、取代芳基、杂烷基和杂芳基的群体,通过包括如通式(I)所示的新型前体化合物在内的途径进行,各种取代选项均适用于产生上述通式(III)中显示的取代基。
