摘要:
Disclosed herein is the selective synthesis of mono-hydrosilylated derivatives of polyunsaturated compounds, such as trivinylcyclohexane using non-precious metal based pyridinediimine and terpyridine complex as selective hydrosilylation catalysts.
摘要:
Disclosed herein is a process for the hydrosilylation 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 silyl 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 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 is the use of manganese, iron, cobalt, or nickel complexes containing tridentate pyridine di-imine ligands as hydrosilylation catalysts. These complexes are effective for efficiently catalyzing hydrosilylation reactions, as well as offering improved selectivity and yield over existing catalyst systems.
摘要:
Silicone compositions that are functionalized with 1,2 or 1,3 glycol bearing-substituents render antiperspirant salts soluble, partially soluble therein or partially miscible therewith. Such functionalized silicones in conjunction with antiperspirant salts produce clear antiperspirant gel sticks.
