The ability to carry out transition-metal-catalyzed copolymerizations of olefins with polar monomers is a great challenge in the field of olefin polymerization. Palladium has been the dominant player in this field, while its low-cost nickel counterpart has only achieved very limited success. We report the synthesis and evaluation of a highly versatile platform based on diphosphazane monoxide ligands. Both palladium and nickel catalysts bearing these ligands mediate the copolymerization of ethylene with a number of fundamental polar monomers.
能够实现烯烃与极性单体的过渡金属催化共聚是烯烃聚合领域的一大挑战。钯在该领域占据主导地位，而其低成本的镍对应物仅取得了非常有限的成功。我们报告了一种基于双膦氮氧化物配体的多功能平台的合成和评价。这些配体负载的钯和镍催化剂都可以介导乙烯与许多基本的极性单体的共聚。
