  Nickel‐Catalyzed Cross‐Redistribution between Hydrosilanes and Silacyclobutanes

  摘要：

  AbstractSilanes are important in chemistry and material science. The self‐redistribution of HSiCl3 is an industrial process to prepare SiH4, which is widely used in electronics and automobile industries. However, selective silane cross‐redistribution to prepare advanced silanes is challenging. We now report an enthalpy‐driven silane cross‐redistribution to access bis‐silanes that contain two different types of Si−H bonds in the same molecule. Compared with entropy‐driven reactions, the enthalpy‐driven reaction shows high regioselectivity, broad substrate scope (62 examples) and high atom economy. Our combined experimental and computational study indicates that the reaction proceeds through a Ni0‐NiII‐NiIV catalytic cycle.

  Dimerization of silacyclobutanes has been achieved under palladium catalysis at room temperature. A previous report described the requirement for high temperature and a stoichiometric amount of palladium complex to effect this process. (C) 2015 Elsevier B.V. All rights reserved.
