Abstract

Si-H bonds can be activated by organozinc and silylzinc compounds in the presence of minute amounts of radical initiators such as tBu ₂Hg or AIBN, yielding zinciosilanes in good yields (see scheme). Activation of dihydridosilanes leads to geminal dizinciosilanes. Zincio-bridged disilyllithium compounds, which have three (1) and four metal-silicon bonds, were also synthesized.
