The present invention is directed to a selective and efficient process for the hydrosilylation of compounds containing terminally unsaturated 1,3-dienes using iron-based hydrosilylation catalysts. The resulting 1,2-addition products are useful as precursors for various silicone materials or silane- or silyl/silicone-functionalized polyolefins.

Selective 1,2-hydrosilylation of terminally unsaturated 1,3-dienes using iron catalysts

Disclosed herein are cobalt complexes containing terdentate pyridine di-imine ligands and their use as efficient, reusable, and selective dehydrogenative silylation, crosslinking, and tandem dehydrogenative silylation-hydrogenation catalysts.

The present invention relates to processes for the synthesis of saturated and unsaturated silahydrocarbons using iron-containing or cobalt-containing catalysts. The processes of the invention can produce tetraalkylsilanes, phenyltrialkylsilanes, substituted phenyltrialkylsilanes and their mixtures, which are useful as lubricants and hydraulic fluids, as well as alkyl alkenylsilanes, phenyl alkenylsilanes and substituted phenyl alkenylsilanes and their mixtures, which are useful in the synthesis of saturated silahydrocarbons and other organofunctional silanes.
