Metal catalyzed olefin hydrosilylation and metal mediated olefin polymerization are both of great academic and industrial importance. In this article, these two aspects are combined to prepare silicon-functionalized polyolefin materials. First, pyridine-diimine cobalt-catalyzed dehydrogenative silylations of various terminal olefins with alkylsilanes lead to the formation of a variety of allylsilanes at high yields. Then, the allylsilanes are copolymerized with ethylene using an α-diimine nickel catalyst, leading to the formation of branched polyolefins with high molecular weight and moderate comonomer incorporation. This subsequent catalytic process is an efficient strategy for the synthesis of silicon-functionalized polyolefins using widely available and inexpensive starting materials.

金属催化的烯烃氢化硅烷化和金属介导的烯烃聚合均具有重要的学术和工业意义。本文结合这两个方面制备了硅功能化聚烯烃材料。首先，吡啶二亚胺钴催化的各种末端烯烃与烷基硅烷的脱氢甲硅烷基化导致以高产率形成各种烯丙基硅烷。然后，使用α-二亚胺镍催化剂将烯丙基硅烷与乙烯共聚，从而形成具有高分子量和适度共聚单体结合的支化聚烯烃。这种随后的催化过程是使用广泛可用且廉价的起始材料合成硅功能化聚烯烃的有效策略。
