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 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.
摘要:
Disclosed herein are manganese, iron, cobalt, or nickel complexes containing terdentate pyridine diimine ligands and their use as efficient and selective hydrosilylation catalysts.
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:
There is provided a fast curing composition comprising an alpha, beta-unsaturated amidocontaing organosilicon compound, useful in making water absorbing silicone -hydrogel films for biomedical devices, such as contact lens, and a process for producing these monomers. This invention also provides for hydrogels made from the alpha, beta-unsaturated amidocontaing organosilicon compound described herein.
