  Synthesis of Kinetically Stabilized 1,2-Dihydrodisilenes

  摘要：

  Kinetically stabilized 1,2-dihydrodisilenes were successfully synthesized and isolated by the introduction of sterically protecting bulky aryl groups. These 1,2-dihydrodisilenes exhibit distinct Si=Si double-bond character in both solution and the solid state. The Si H bonds in these 1,2-dihydrodisilenes exhibit higher s character than those of typical sigma(4),lambda(4)-hydrosilanes. Moderate heating of these 1,2-dihydrodisilenes in solution resulted in their isomerization to the corresponding trihydrodisilanes, with an intramolecular hydrogen migration as the rate-determining step.
