Cationic zirconium complexes in situ generated from zirconium dibenzyl complexes bearing amine-bridged bis(phenolato) ligands have been developed to catalyze addition of C(sp)-H and C(sp)-H bonds of pyridine derivatives to alkenes. A series of zirconium complexes bearing different ligands have been synthesized, and their activities in catalyzing addition of C(sp)-H bonds of pyridine derivatives to alkenes have been studied and compared. Both reaction activity and regioselectivity are influenced by electronic and steric properties of ligand backbones. In addition, a cationic zirconium complex has been isolated and structurally characterized to shed some light on reaction mechanism.
由带有胺桥联双（苯酚）配体的二苄基锆配合物原位生成的阳离子锆配合物已被开发用于催化吡啶衍生物的 C(sp)-H 和 C(sp)-H 键与烯烃的加成。合成了一系列带有不同配体的锆配合物，并研究和比较了它们催化吡啶衍生物的 C(sp)-H 键与烯烃加成的活性。配体骨架的电子和空间性质都会影响反应活性和区域选择性。此外，还分离和结构表征了一种阳离子锆配合物，以阐明反应机理。
