Abstract: 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.

Abstract: 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.

Abstract: The invention relates to a method for producing MoO2Cl2 under inert conditions, comprising the steps of:



(i) charging a reaction vessel with MoO2,
(ii) reacting the MoO2 with supplied Cl2 in the reaction vessel at a first temperature T1 to give gaseous MoO2Cl2,
(iii) transferring the gaseous MoO2Cl2 into a receiving vessel,
(iv) resublimating the gaseous MoO2Cl2 in the receiving vessel to give solid MoO2Cl2 at a second temperature T2 that is lower than T1, and
(v) recovering solid MoO2Cl2 with a purity determined by ICP-OES/MS of 99.9996 wt. % or more.




The invention also relates to high-purity MoO2Cl2, the use thereof, and electronic components.
