is very unselective, leading to multiple side products. Herein, we describe a new catalytic hydrogenation of oligo‐ and polysilanes that is highly selective and proceeds under mild conditions. New low‐valent nickel hydride complexes are used as catalysts and secondary silanes, RR′SiH2, are obtained as products in high purity.
在Si-Si键形成下有机硅烷(R x SiH 4- x)的脱氢反应是引起广泛研究的导致低聚硅烷或聚硅烷的过程。对逆反应的研究很少。迄今为止,Si-Si键的氢解需要非常苛刻的条件,并且非常无选择性,导致产生多种副产物。在这里,我们描述了一种新的低聚硅烷和聚硅烷的催化加氢方法,该方法具有很高的选择性,并在温和的条件下进行。新型低价氢化镍配合物用作催化剂,仲硅烷RR'SiH 2作为高纯度产品获得。

cooperative [M]-/Organo-catalytic systems in aerobic Si−H− to Si−OH-group oxidation showed the efficiency of the two “complementary” catalytic systems, based on earth-abundant [M]-catalysts and inexpensive commercially available organic catalysts. [Co]/NHSI (A) system made it possible to oxidize a wide range of monomers but failed in the case of oligomeric and polymeric substrates. This problem was solved
