Silicon(II) Cation Cp*Si:+ X–: A New Class of Efficient Catalysts in Organosilicon Chemistry

posted on 2019-10-13, 12:14 authored by Elke Fritz-LanghalsThe catalytic activity
of the pentamethylcyclopentadienylsilicon(II)
cation Cp*Si:+ was investigated. It was shown that Cp*Si:+ efficiently catalyzes reactions of technical relevance in
organosilicon chemistry: Cp*Si:+ proved to be a very efficient
nonmetallic catalyst for the hydrosilylation of olefins at low catalyst
amounts of <0.01 mol % and for the Piers–Rubinsztajn reaction
in order to make controlled silicone topologies. The thermal induction
of hydrosilylation which is important for the manufacturing of silicone
rubber can be achieved by small amounts of alkoxysilanes.
