Over the past two decades, intensive efforts have been devoted to the development of group-10 metal catalysts, especially nickel and palladium ligated by unsymmetric bidentate ligands aimed at the copolymerization of olefins with polar monomers. Here we synthesized a palladium complex bearing a methoxyethoxygroup and applied it to the copolymerization of ethylene and methyl acrylate. Higher incorporation of methyl acrylate was detected in the presence of lithium borate such as LiBArF4. The effect was limited to lithium, and the counteranion also affected the catalyst performance.

带有含甲氧基乙基醚部分的 IzQO 配体的钯催化剂共聚乙烯和丙烯酸甲酯以及聚合的盐效应

在过去的二十年中，人们致力于开发第 10 族金属催化剂，特别是通过不对称双齿配体连接的镍和钯，旨在烯烃与极性单体的共聚。在这里，我们合成了一种带有甲氧基乙氧基的钯配合物，并将其应用于乙烯和丙烯酸甲酯的共聚反应。在硼酸锂如 LiBArF4 存在下检测到丙烯酸甲酯的更高掺入。影响仅限于锂，反阴离子也影响了催化剂的性能。
