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.
