The invention relates to a bridged bi-aromatic phenol ligand of formula (I) or (IX)
or
wherein each of R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13 and R14 is independently selected from the group consisting of hydride, halide, optionally substituted hydrocarbyl, heteroatom-containing optionally substituted hydrocarbyl, alkoxy, aryloxy, silyl, boryl, dialkyl amino, alkylthio, arylthio and seleno; optionally two or more R groups can combine together into ring structures with such ring structures having from 3 to 100 non-hydrogen atoms in the ring; A is a bridging group having from one to 50 non-hydrogen atoms; Y and Y' are independently selected from O, S, NRa and PRa wherein Ra is optionally substituted hydrocarbyl; Ar is optionally substituted aryl or optionally substituted heteroaryl, prepared by a method which comprises preparing the ligand from a compound containing at least one phenol moiety wherein the at least one phenol moiety remains unprotected during all steps of the method and the method comprises at least one step of aryl coupling.
本发明涉及式 (I) 或 (IX) 的桥接双芳香族酚配体
或
其中 R1、R2、R3、R4、R5、R6、R7、R8、R9、R10、R11、R12、R13 和 R14 各自独立地选自由氢化物、卤化物、任选取代的烃基、含杂原子的任选取代的烃基、烷氧基、芳氧基、硅烷基、硼烷基、二烷基氨基、烷硫基、芳硫基和硒基组成的组;两个或两个以上的 R 基团可任意组合成环状结构,环状结构中含有 3 至 100 个非氢原子;A 是桥基,具有 1 至 50 个非氢原子;Y 和 Y'独立选自 O、S、NRa 和 PRa,其中 Ra 是任选取代的烃基;Ar 是任选取代的芳基或任选取代的杂芳基,制备方法包括从含有至少一个酚基的化合物中制备配体,其中至少一个酚基在该方法的所有步骤中保持未受保护,且该方法包括至少一个芳基偶联步骤。
