  区域发散的氢化硅烷化，氢化，[2π+2π]-环加成反应和使用抗衡离子活化的土壤富集金属催化的C–H硼化†

  摘要：

  由于产生活性低氧化态催化剂所需的通常具有挑战性的实际要求，富含地球的金属催化的广泛采用落后于第二行和第三行的过渡金属。在这里，我们报告了使用铁和钴的预催化剂跨越五个反应类别的单一内源性活化方案的发展。这种简单的催化歧管使用市售的板凳稳定的四氟硼酸铁或钴盐进行区域发散性的烯烃和炔烃氢化硅烷化，1,3-二烯氢化硅烷化，氢化，[2π+2π]-环加成和CHH硼化。通过氟化物从抗衡离子上解离，原位形成氢化活化剂并生成低氧化态催化剂来进行活化。

• Iron-Catalysed Chemo-, Regio-, and Stereoselective Hydrosilylation of Alkenes and Alkynes using a Bench-Stable Iron(II) Pre-Catalyst

  AbstractThe chemo‐, regio‐, and stereoselective iron‐catalysed hydrosilylation of alkenes and alkynes with excellent functional group tolerance is reported (34 examples, 41–96% yield). The catalyst and reagents are commercially available and easy to handle, with the active iron catalyst being generated in situ, thus providing a simple and practical methodology for iron‐catalysed hydrosilylation. The silane products can be oxidised to the anti‐Markovnikov product of olefin hydration, and the one‐pot iron‐catalysed hydrosilylation–oxidation of olefins to give silane(di)ols directly is also reported. The iron pre‐catalyst was used at loadings as low as 0.07 mol%, and displayed catalyst turnover frequencies (TOF) approaching 60,000 mol h−1. Initial mechanistic studies indicate an iron(I) active catalyst.magnified image

  The N-heterocyclic carbene (NHC) nickel complexes [(L)Ni(NHC)][BAr4F] (Ar-F = 3,5-bis(trifluoromethyl)-phenyl; L = allyl (1), methylallyl (2); NHC = 1-(2-picolyl)-3-methylimidazol-2-ylidene (a), 1-(2-picolyl)-3-isopropylimidazol-2-ylidene (b), 1-(2-picolyl)-3-n-butylimidazol-2-ylidene (c), 1-(2-picolyl)-3-phenylimidazol-2-ylidene (d), 1-(2-picolyl)-3-methylbenzoimidazol-2-ylidene (e), 1-(2-picolyl)-4,5-dichloro-3-methylimidazol-2-ylidene (0) have been obtained in high yields and characterized by NMR spectroscopy. Furthermore, Id was unambiguously characterized by single-crystal X-ray crystallography. Complexes 1a-f/2a-f have shown catalytic activity toward dimerization and hydrosilylation of styrenes. In particular, 1a proved to be the most efficient catalyst in the dimerization of styrene derivatives in the absence of cocatalyst. Also, complexes 1a,d showed high selectivity and moderate to good yields in hydrosilylation reactions.
