The noncovalent interactions and remote ligand effects in catalysis have attracted a large attention in the last years. The rationalization of such interactions is tricky and often their role can be elucidated only with a detailed mechanistic study. Here we report the case of fluorinated ligand systems showing a very peculiar behavior in the catalysis of olefin polymerization. The results reported aim to clarify the origin of such behavior underlying the nature of the control of the fluorinated groups on the key steps of the polymerization. These insights can offer new cues to rationalize similar evidences in other reaction fields.

非共价相互作用在烯烃聚合催化中的作用：进一步研究氟化配体的作用

近年来，催化中的非共价相互作用和远程配体效应引起了广泛的关注。这种相互作用的合理化是棘手的，通常只有通过详细的机理研究才能阐明它们的作用。在这里，我们报告氟化配体系统在烯烃聚合催化中表现出非常特殊的行为。报道的结果旨在阐明在聚合关键步骤上控制氟化基团性质的这种行为的根源。这些见解可以提供新的线索，以合理化其他反应领域中的类似证据。
