标 题 :Process for the Synthesis of Amine Ethers
发明人：FREY MARKUS; BROENNIMANN VALERIE
权利人:CIBA GEIGY CORP
摘要:The present invention relates to novel processes for the preparation of a sterically hindered amine ether by reacting a corresponding sterically hindered amine oxide with a ketone or an aldehyde with at least one reactive H in the presence of a peroxydisulphate. Products obtained by this process may be hydrogenated. The compounds made by these processes are particularly effective in the stabilization of polymer compositions against harmful effects of light, oxygen and/or heat and as flame-retardants for polymers.

摘要:Hexacoordinated ruthenium and osmium catalysts of the formulae in which M and M' independently of one another are ruthenium or osmium; X, X', Y and Y' independently of one another are anionic ligands, or X and Y and X' and Y' in each case together are bis-anionic ligands L1 and L1' independently of one another are tertiary phosphine; L2 and L3 independently of one another are a monodentate ligand, or L2 and L3 together are bidentate, neutral electron donor ligands; L4 is tetradentate, neutral electron donor ligand; L5 is a bidentate, neutral electron donor ligand; and T and T' indepedently of one another are H or organic substituents, are useful for the synthesis of custom-tailored polymers and for the ring-closing metathesis of olefins.
