    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: The invention relates to the preparation of aliphatic-aminonitriles by partial hydrogenation of aliphatic dinitriles atelevated temperature and higher pressure, in the presence of asolvent and catalyst. Catalyst, containing the following is used:(a) compound based on metal, e.g. nickel, cobalt, iron, rutheniumand rhodium; (b) from 0.01 to 25 wt.% promotor to component (a)based on metal such as palladium, platinum, iridium, osmium,copper, silver, gold, chromium, molybdenum, tungsten, manganese,rhenium, zinc, cadmium, lead, aluminium, tin, phosphorus, arsenic,antimony, bismith, silicon, titanium, zirconium and the rare earthelements, and (c) from 0 to 5 wt.% compound to component (a) basedon alkali or alkaliearth metal, provided that component (a) isdifferent from an iron-based compound or from iron, as well asfrom the metals cobalt, ruthenium or rhodium when component (b) ispromotor based on a metal from the group containing titanium,managanese, chromium and molybdenum. An additional condition isthat when component (a) is a compound based on ruthenium orrhodium separately, or of ruthenium and rhodium, or of nickel andrhodium, promotor (b) can optionally be dropped.
