Nickel complexes with N,O-chelating ligands turned out to be promising catalysts in that field. In this work a series of new N,O ligands with an electronically delocalised β-enaminone backbone were synthesised and fully characterised. The ligand design was inspired by the ligand found in the most efficient nickel catalyst for polyketone synthesis and developed to a highly modular LEGO®-like arsenal of
聚酮是通过过渡金属催化的烯烃和一氧化碳的共聚反应合成的。镍与 N,O 螯合配体的配合物被证明是该领域有前途的催化剂。在这项工作中,合成并充分表征了一系列具有电子离域 β-烯胺酮骨架的新 N,O 配体。配体设计的灵感来自于最有效的聚酮合成镍催化剂中发现的配体,并开发为高度模块化的 LEGO® 类反应库,用于多功能取代的 β-烯胺酮配体。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
