  (COT)2Fe and the open ferrocenes (MPDE)2Fe (MPDE = η5-3-methylpentadienyl) and (DMPDE)2Fe (DMPDE = η5-2,4-dimethylpentadienyl) were found to function as catalyst precursors for the hydrosilylation of alkenes in the presence of auxiliary ligands. Screening trials determined that the optimal catalyst system was composed of (COT)2Fe and adamantyl isocyanide, allowing the selective hydrosilylation of styrene

  （COT）2 Fe和开放二茂铁（MPDE）2的Fe（MPDE =η 5 -3- methylpentadienyl）和（DMPDE）2的Fe（DMPDE =η 5 -2,4-二甲基戊）被发现作为用于催化剂前体在辅助配体存在下烯烃的氢化硅烷化。筛选试验确定，最佳催化剂体系由（COT）2 Fe和金刚烷基异氰化物组成，可以使苯乙烯衍生物与三取代氢硅氧烷和带有Me 2的聚二甲基硅氧烷进行选择性氢化硅烷化SiH部分作为端基。在适当的条件下，脱氢甲硅烷基化副反应被完全抑制，反应TON超过5000。

  High-spin pyridine diimine cobalt(II) bis(carboxylate) complexes have been synthesized and exhibit high activity for the hydrosilylation of a range of commercially relevant alkenes and tertiary silanes. Previously observed dehydrogenative silylation is suppressed with the use of sterically unencumbered ligands, affording exclusive hydrosilylation with up to 4000 TON. The cobalt precatalysts were readily
