    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: Prepn. of 1,2,4-triazolium salts of formula (Ia) and 1,2,4-triazolines of formula (Ib) comprises (a) reacting an amidrazone of formula (R )(NHR )C=N-NHR (II) with a carboxylic acid of formula R COOH (III) or its functional deriv. (IIIa) to give (Ia; A = anion of (III)), opt. followed by exchanging the anion for another A; and opt. (b) reacting (Ia), without isolation, with an alcohol or thiol cpd. of formula X-Y-R (IV) to give (Ib). R -R , R = organic gps., where R , R may be linked to form a 5-8 membered ring; R = H or organic gp.; A = 1 equiv. of an anion; Y = O or S ; X = H, alkali metal or alkaline earth metal.

    Abstract: Preparation of amidoalkylmelamines and aminoalkylmelamines of the formula I I where R1 is an amidoalkyl group -(CH2)n-NHZ or an aminoalkyl group -(CH2)n-NH2, n is from 2 to 10, preferably from 2 to 6, Z is an amino protective group and R2 and R3 independently of one another are each hydrogen or have the same meanings as R1, are prepared by a process in which a chlorotriazine is reacted with a diamine of the formula H2N-(CH2)n-NHZ, where n and Z have the above meanings, to give an amidoalkylmelamine, and, if required, the group Z is eliminated.
