  • Hydrosilylation reaction catalysts and curable compositions and methods for their preparation and use
    Patent number: 9073950
    Abstract: A composition contains (A) a hydrosilylation reaction catalyst and (B) an aliphatically unsaturated compound having an average, per molecule, of one or more aliphatically unsaturated organic groups capable of undergoing hydrosilylation reaction. The composition is capable of reacting via hydrosilylation reaction to form a reaction product, such as a silane, a gum, a gel, a rubber, or a resin. Ingredient (A) contains an iron-organosilicon ligand complex that can be prepared by reacting an iron carbonyl compound and an organosilicon ligand.
