摘要:
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.
摘要:
Disclosed herein is a process for the hydrasilylation of a composition containing a silyl hydride and a compound containing at least one unsaturated group, the process comprising contacting a non-previous metal based complex as a catalyst precursor with an activator being a reducing agent shortly before, simultaneously or after contacting the complex with the composition, to cause the siiyl hydride to react with the compound containing at least one unsaturated group to produce a hydrosilylation product.
摘要:
Disclosed herein are manganese, iron, cobalt, or nickel complexes containing 2,8- bis(imino)quinoline ligands and their use as catalysts or catalysts precursors for hydrosilylation reactions.
摘要:
Disclosed herein is the selective synthesis of mono-hydrosilylated derivatives of polyunsaturated compounds, such as trivinylcyclohexane using non-precious metal based pyridined limine and terpyridine complex as selective hydrosilylation catalysts.
