    Abstract: Aliphatic alpha,omega-aminonitriles are prepared by partial hydrogenation of aliphatic alpha,omega-dinitriles at elevated temperatures and superatmospheric pressure in the presence of a solvent and of a catalyst by a process which comprises using a catalyst which (a) contains a compound based on a metal selected from the group consisting of nickel, cobalt, iron, ruthenium and rhodium and (b) contains from 0.01 to 25% by weight, based on (a), of a promoter based on a metal selected from the group consisting of palladium, platinum, iridium, osmium, copper, silver, gold, chromium, molybdenum, tungsten, manganese, rhenium, zinc, cadmium, lead, aluminum, tin, phosphorus, arsenic, antimony, bismuth and rare earth metals and (c) from 0 to 5% by weight, based on (a), of a compound based on an alkali metal or on an alkaline earth metal. with the proviso that the component (a) is not based on iron or iron and one of the metals selected from the group consisting of cobalt, ruthenium and rhodium when (b) is a promoter based on a metal selected from the group consisting of titanium, manganese, chromium and molybdenum, and with the further proviso that, when a compound based on only ruthenium or rhodium or ruthenium and rhodium or nickel and rhodium is selected as component (a), the promoter (b) may be dispensed with.

    Abstract: Aliphatic alpha , omega -aminonitriles are prepared by partial hydrogenation of aliphatic alpha , omega -dinitriles at elevated temperatures and superatmospheric pressure in the presence of a solvent and of a catalyst, by a process in which the catalyst used is obtainable by thermal decomposition of a metal compound selected from the group consisting of metal carbonyl compounds, metal salts of C1-C6-carboxylic acids and C2-C6-dicarboxylic acids and metal complexes with diketones to give the corresponding metal and/or a metal oxide thereof, with the proviso that the metal used is nickel or cobalt.

    Abstract: A process is proposed for producing acyloines of general formula (I) in which Ra and Rb are identical or different and represent hydrogen or a C1-C20 alkyl, a C6-C10 aryl, a C7-C12 aralkyl, a heteroaryl, or a heterocycloalkyl group, these groups being substituted if appropriate, with the exception of formaldehyde autocondensation products. In the proposed process, an aldehyde of formula (II) RaCHO is allowed to react with an aldehyde of formula (III) RbCHO, in which Ra and Rb have the meanings indicated above and at least one of the groups Ra and Rb represents a group other than hydrogen, in the presence of catalysts produced using an auxiliary base from triazolium salts of formula (IV) in which R1 and R3 are identical or different and represent aliphatic groups with 1-30 carbon atoms, or, if appropriate, aryl groups, aralkyl groups and/or heteroaryl groups, these groups being substituted if appropriate; R2 represents hydrogen or the group RbCH(OH); and A is the equivalent of a singly or multiply negatively charged anion for the electrical neutralisation of the triazolium cation charge.
