Abstract
A catalyst for hydrosilylation is disclosed. The catalyst comprises a complex having a certain formula. A redox-switchable catalyst system for preparing the catalyst is also disclosed. The redox-switchable catalyst system comprises a redox-switchable catalyst and a reducing compound. The reducing compound reduces a formal oxidation state of the redox-switchable catalyst to give the catalyst, where the former is generally inactive in catalyzing hydrosilylation and the latter is catalytically active. A composition comprising the catalyst and/or the redox-switchable catalyst system, and a hydrosilylation reaction product, are also disclosed.
