20110034713 | Ortho-metalated, chelate-stabilized benzylamines of the rare-earth metals (RE) Ar3RE - The present invention describes homoleptic, ortho-metalated, chelate-stabilized benzylamine complexes of the rare-earth metals. The rare-earth metals are selected from Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu. In the complexes according to the present invention, at least one benzylic proton of the benzylamine ligand is replaced by an alkyl or aryl group. Such complexes are preferred in which both benzylic protons of the benzylamine ligand are replaced by an alkyl- or aryl group. The complexes according to the present invention are produced by reaction of chelate-stabilized rare-earth metal halides with ortho-lithiated aryl ligands at room temperature under inert gas atmosphere. The complexes according to the present invention are thermally stable and suitable for being used as catalysts for the hydroamination of olefins. | 02-10-2011 |
20110034715 | Cyclopentadienylphosphazene complexes (CpPN Complexes) of metals of the third and fourth group and of the lanthanoids - The present invention concerns cyclopentadienylphosphazene complexes (CpPN complexes) of the metals of the third and fourth group and of the lanthanoids with the exception of lutetium. The complexes according to the present invention are isolobal and isoelectronic to [(CpSiN)TiR | 02-10-2011 |
20120264668 | DETERGENTS OR CLEANING AGENTS CONTAINING A BLEACH-ENHANCING TRANSITION METAL COMPLEX WHICH IS OPTIONALLY PRODUCED IN SITU - A bleach catalyst includes a complex of Fe—, Mo—, Mn— and/or W with a ligand having a skeleton of formula (I). | 10-18-2012 |
20120264670 | DETERGENTS OR CLEANING AGENTS CONTAINING A BLEACH-ENHANCING TRANSITION METAL COMPLEX WHICH IS OPTIONALLY PRODUCED IN SITU - The aim of the invention is to improve the cleaning power of detergents and cleaning agents, especially with regard to bleachable stains, while avoiding any damage to the textile treated with said detergents and cleaning agents. For this purpose, a bleach catalyst in the form of a complex of Fe—, Mo—, Mn— and/or W with a ligand having a skeleton of formula (I) is used. | 10-18-2012 |
20130303740 | METHOD FOR PRODUCING URETHANES - The invention relates to a method for producing urethanes or ureas or mixtures of urethanes and ureas by oxidative carbonylation of organic amines in the presence of carbon monoxide, oxygen and a catalyst, where the catalyst used is a transition metal complex containing the structural feature: [Mn+(O˜N˜O)2−](n-2)+(L)m(Z−)n-2 and the method is carried out under halogen-free reaction conditions. The invention further relates to transition metal complexes containing said structural feature and also to the use of such transition metal complexes as catalysts in the production of urethanes or ureas or mixtures of urethanes and ureas. | 11-14-2013 |
