Abstract: The present invention relates to a process for the preparation of an optically active carbonyl compound by asymmetric hydrogenation of a prochiral α,β-unsaturated carbonyl compound with hydrogen in the presence of at least one optically active transition metal catalyst that is soluble in the reaction mixture and which has rhodium as catalytically active transition metal and a chiral, bidentate bisphosphine ligand, wherein the reaction mixture during the hydrogenation of the prochiral α,β-unsaturated carbonyl compound additionally comprises at least one compound of the general formula (I): in which R1, R2: are identical or different and are C6- to C10-aryl which is unsubstituted or carries one or more, e.g. 1, 2, 3, 4 or 5, substituents which are selected from C1- to C6-alkyl, C3- to C6-cycloalkyl, C6- to C10-aryl, C1- to C6-alkoxy and amino; Z is a group CHR3R4 or aryl which is unsubstituted or carries one or more, e.g. 1, 2, 3, 4 or 5, substituents which are selected from C1- to C6-alkyl, C3- to C6-cycloalkyl, C6- to C10-aryl, C1- to C6-alkoxy and amino, wherein R3 and R4 are as defined in the claims and the description.

Abstract: A catalytic process for preparing an α,β-ethylenically unsaturated carboxylic acid salt from an alkene, carbon dioxide and an alkoxide having a secondary or tertiary carbon atom directly bound to a [O—] group is described. The alcohol byproduct is distilled off after an intermediate phase separation. This provides pure β,β-ethylenically unsaturated carboxylic acid salt at minimum effort.

Abstract: The present invention is in the field of processes for the generation of thin inorganic films on substrates, in particular atomic layer deposition processes. In detail the present invention relates a process comprising bringing a compound of general formula (I) into the gaseous or aerosol state (Fig.) and depositing the compound of general formula (I) from the gaseous or aerosol state onto a solid substrate, wherein R1 and R4 are independent of each other an alkyl group, an aryl group or a trialkylsilyl group, R2, R3, R5 and R6 are independent of each other hydrogen, an alkyl group, an aryl group or a trialkylsilyl group, n is an integer from 1 to 3, M is Ni or Co, X is a ligand which coordinates M, and m is an integer from 0 to 4.
