Karstedt's catalyst
Karstedt's catalyst is an organoplatinum compound derived from divinyl-containing disiloxane. This coordination complex is widely used in hydrosilylation catalysis. It is a colorless solid that is generally assumed to be a mixture of related Pt(0) alkene complexes. The catalyst is named after Bruce D. Karstedt, who developed it in the early 1970s while working for General Electric.
==Applications==
Carbon-silicon bonds are created via hydrosilylation reactions. This reaction has very important applications to industry. While it is favorable thermodynamically, hydrosilylation does not proceed in the absence of a catalyst. It is produced by treatment of chloroplatinic acid by the divinyltetramethyldisiloxane.
The catalyst can also be used in a reductive amination reaction between a carboxylic acid and an amine with phenylsilane as the reducing agent.
