摘要： The invention relates to a method for preparing compounds of the general formula MAYn(AzuH) (I), where MA=alkali metal, Y=neutral ligand, n=0, 1, 2, 3, or 4. AzuH is azulene (bicyclo[5.3.0]decapentaene) or an azulene derivative that bears a hydride anion H− in the 4, 6 or 8 position in addition to an H atom. The invention additionally provides compounds obtainable by this method, and a method using such compounds for preparation of complexes of metals of groups 6 to 12. The invention further relates to complexes of middle and later transition metals (groups 6 to 12) which each have at least one H-dihydroazulenyl anion (AzuH)1−, and to the use of all the aforementioned transition metal complexes as precatalysts or catalysts or electron transfer reagents in a chemical reaction or as precursor compounds for production of a layer containing a metal M, or of a metal layer consisting of the metal M, especially on at least one surface of a substrate. The invention also provides a substrate obtainable by such a method. 25

摘要： The invention is directed to ruthenium-based metathesis catalysts of the Grubbs-Hoveyda type. The new 2-aryloxy-substituted ruthenium catalysts described herein reveal rapid initiation behavior. Further, the corresponding styrene-based precursor compounds are disclosed. The catalysts are prepared in a cross-metathesis reaction starting from styrene-based precursors which can be prepared in a cost-effective manner.
The new Grubbs-Hoveyda type catalysts are suitable to catalyze ring-closing metathesis (RCM), cross metathesis (CM) and ring-opening metathesis polymerization (ROMP). Low catalyst loadings are necessary to convert a wide range of substrates including more complex and critical substrates via metathesis reactions at low to moderate temperatures in high yields within short reaction times.-

摘要： The invention relates to a wall-flow filter as a particle filter with catalytically active coatings in the channels which are closed in a gas-tight manner at the opposing closed ends of the channels A at the first end, wherein the inlet region of the filter is additionally supplied with a dry powder-gas aerosol which contains metal compounds with a high melting point (such as the metal oxides Al2O3, SiO2, FeO2, TiO2, ZnO2, etc. for example) and which is to simultaneously improve the catalytic activity and the degree of filtration efficiency with respect to the exhaust gas back-pressure.
