Catalytic amounts of lanthanide(III) triflates promote reactions between amines and nitriles leading to a variety of products.The Ln3+ ions activate weakly coordinating nitriles at large amine: Ln3+ mole ratios, even in the presence of amines that form thermodynamically stable complexes with Ln3+ ions.The reactions involving primary monoamines and diamines appear to be general and provide a viable synthetic route to N,N'-disubstituted amidines (2) and cyclic amidines (4), respectively.Symmetrically substituted triazines (8 or 9) are observed as byproducts in some of these systems when the reactions are carried out by using excess nitrile.Secondary alicyclic amines or dimethylamine reacts with acetonitrile to yield pyrimidines (6) and 2,4,6-trimethyl-s-triazine (8).Two routes to triazine have been proposed, one involving the reaction of ammonia with the nitrile and the second involving the reaction of an amidine (1 or 5) with the nitrile.The ability of Ln3+ ions to activate nitriles under conditions that oppose nitrile coordination is attributed to the lability of Ln3+ complexes derived from N-donors.

The reaction of 1-diethylamino- and 1-(ethylphenylamino)-1-propynes with aromatic and aliphatic bifunctional reagents was invectigated.In the reactions of the ynamines with aromatic binucleophiles and also with ethenolamine and ethylenediamine heterocyclic compounds of the benzodioxole, benzimidazoline, benzoxazole, benzothiazole, oxazoline, and imidazoline series are formed.The reactions of the ynamines with ethylene glycol and dithioglycol gave amino(alkoxy)alkenes and amino(alkylthio)-alkenes.
