  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

  高旋转吡啶二亚胺钴（II）双（羧酸盐）配合物已经合成，并显示出高活性，可用于一系列商业上相关的烯烃和叔硅烷的氢化硅烷化。以前观察到的脱氢甲硅烷基化可通过使用空间不受阻碍的配体来抑制，从而提供高达4000 TON的排他性氢化硅烷化。钴预催化剂易于制备并在工作台上进行处理，并进行了底物活化，从而无需使用外部还原剂。钴催化剂对环氧化物，氨基，羰基和烷基卤化物的官能团具有耐受性，从而拓宽了用富含土壤的金属催化剂进行烯烃氢化硅烷化的范围。

  A process for producing a silylated product comprises reacting a mixture comprising (a) an unsaturated compound containing at least one unsaturated functional group, (b) a silyl hydride containing at least one silylhydride functional group, and (c) a catalyst, optionally in the presence of a solvent, to produce a dehydrogenative silylated product, a hydrosilylated product, or a combination of a dehydrogenative silylated product and a hydrosilylated product, wherein the catalyst is chosen from a pyridine diimine cobalt dicarboxylate complex or a cobalt carboxylate compound, and the process is conducted without pre-activating the catalyst via a reducing agent and/or without an initiator or promoter compound. The present catalysts have been found to be active in the presence of the silyl hydride employed in the silylation reaction.

  capable of catalyzing alkene hydrosilylation in the absence of external activators are rarely known, and their activation mode has remained poorly understood. We present here that cobalt(II) amide complexes, [Co(N(SiMe3)2)2] and its NHC adducts [(NHC)Co(N(SiMe3)2)2] (NHC = N-heterocyclic carbene), are effective catalysts for the hydrosilylation of alkenes with tertiary silanes. Mechanistic studies

  在没有外部活化剂的情况下能够催化烯烃氢化硅烷化的钴 (II) 配合物很少为人所知，并且其活化模式仍然知之甚少。我们在此提出钴 (II) 酰胺配合物 [Co(N(SiMe3)2)2] 及其 NHC 加合物 [(NHC)Co(N(SiMe3)2)2]（NHC = N-杂环卡宾）是烯烃与叔硅烷氢化硅烷化的有效催化剂。机理研究表明，钴 (II) 酰胺可以与氢硅烷反应形成钴 (I) 物质、甲硅烷基酰胺和氢，作为进入真正催化活性物质的入口，大概是钴 (I) 物质，用于钴催化氢化硅烷化反应。

  Several carboxylated polyethylene glycols as promoters were applied in the platinum‐catalyzed hydrosilylation of alkenes, and polyethylene glycol maleic acid monoester as a promoter for hydrosilylation was investigated. It was found that an improvement of the selectivity was achieved in the presence of carboxylated polyethylene glycol, and the β‐adduct as major product was obtained. Additionally, the
