    • A process for preparing a chelating ligand of the formula (II) from a chelating ligand of the formula (I) via an sp2-sp2 or sp2-sp3 coupling reaction with an organometallic compound of the formula (III). wherein B is a bridging group that is bonded to L1 and L2 in formula (I) and to L3 and L4 in formula (II); L1 is a substituted monocyclic or polycyclic ligand that comprises at least one chlorine, bromine, iodine, or sulfonate substituent, directly bonded to an sp2 carbon atom of the ring structure of the ligand; L2 is a monoanionic ligand; or L2 may, independently, be defined as L1; L3 is the same group as L1, but said at least one chlorine, bromine, iodine, or sulfonate substituent is replaced with a hydrocarbyl, substituted hydrocarbyl, halocarbyl, or substituted halocarbyl fragment; L4 is the same group as L2, though, when L2 is defined as L1, L4 may be the same as L3 or L1; R1 is a hydrocarbyl, substituted hydrocarbyl, halocarbyl, or substituted halocarbyl; M1 is an element of group 1, 2, 12, 13 or 14 of the Periodic Table of the Elements; each X2, if present, is selected independently from the group consisting of halogen atoms, the hydroxyl group, alkoxy groups, aryloxy groups, mesylate, tosylate and triflate; r is 1, 2 or 3, and t is 0, 1 or 2, where r+t corresponds to the oxidation number of M1.
    • 通过与式(III)的有机金属化合物的sp2-sp2或sp2-sp3偶联反应从式(I)的螯合配体制备式(II)的螯合配体的方法。 其中B是与式(I)中的L1和L2键合并且在式(II)中与L3和L4键合的桥连基团; L1是取代的单环或多环配体,其包含直接键合到配体的环结构的sp2碳原子上的至少一个氯,溴,碘或磺酸盐取代基; L2是单阴离子配体; 或L2可以独立地定义为L1; L3是与L1相同的基团,但是所述至少一个氯,溴,碘或磺酸酯取代基被烃基取代的烃基,卤代烃基或取代的卤代烃基片段代替; L4与L2相同,但当L2定义为L1时,L4可以与L3或L1相同; R 1是烃基,取代的烃基,卤代烃基或取代的卤代烃基; M1是元素周期表第1,2,12,13或14族的元素; 每个X 2如果存在,独立地选自卤素原子,羟基,烷氧基,芳氧基,甲磺酸酯,甲苯磺酸酯和三氟甲磺酸酯; r为1,2或3,t为0,1或2,其中r + t对应于M1的氧化数。
