Abstract: Urethanes are prepared by oxidative carbonylation of at least one amino compound in the presence of carbon monoxide, oxygen and organic, at least one hydroxyl-group-carrying compound. The carbonylation is carried out in the absence of halogen-containing promoters. The carbonylation is also carried out in the presence of a metal complex catalyst which contains neutral bidentate N-chelate ligands of the (N˜N) type, two monoanionic N,O-chelate ligands of the general type (N˜O)? or tetradentate dianionic chelate ligands (O˜N˜N˜O)2?.

Abstract: The subject of the invention at hand are novel, a little basic, fluorinated pentafluorophenyl imide anions, which can be used as anions in ionic liquids. Methods for producing ionic liquids are described, which contain these novel pentafluorophenyl imide ions as anions, as well as quaternary organic ammonium ions, guanidinium ions, N-organo-pyridinium ions, imidazolium, imidazolidinium or benzimidazolidinium ions, alkyl-alkylidene phosphoranes or aryl-alkylidene phosphoranes as cations. Alternative methods according to the present invention provide ionic liquids through reaction of ketene N,N-diacetals or alkyl or aryl-alkylidene phosphoranes with acids. The ionic liquids according to the present invention are suitable, for example, as solvents for syntheses, as mobile and/or stationary phase in chromatography, as electrolyte systems for batteries, galvanic elements, fuel cells and rechargeable battery packs.

Abstract: The present invention provides new lithium salts comprising pentafluorophenylamide anions following the general formula Li+[N(SO2—R)(C6F5)]?, which are optionally present as solvent-free complexes. R is hereby selected from fluorine, linear or branched acyclic or cyclic alkyl groups with 1 to 20 carbon atoms which are not fluorinated, partially fluorinated or fully fluorinated; or not fluorinated, partially fluorinated or fully fluorinated aryl or benzyl groups with 1 to 20 carbon atoms. The lithium salts according to the present invention are produced by reacting the corresponding NH acid of the pentafluorophenylamide with one equivalent of lithium bis(trimethylsilyl)amide or lithium organyl, wherein the reaction is carried out advantageously in the presence of apolar aprotic solvents. In this way, lithium salts in the form of solvent-free complexes are obtained. These solvent-free lithium complexes are thermally, electrochemically and against oxidation stable and comprise a high ionic conductivity.
