Abstract: A series of 3-(N-arylamino)-5-amino-1Н-1,2,4-triazoles were prepared by the reaction of S,S-dimethyl cyanodithioimidocarbamate with appropriate anilines. The inhibiting effect of the products on the corrosion of copper of M1 grade in acidic and neutral chloride-containing media was studied using electrochemical and accelerated electroless methods. The maximal degree of protection ensured by commercially available 3,5-diamino-1H-1,2,4-triazole and the synthesized 3-phenylamino, 3-(4-methylphenylamino), 3-(4-chlorophenylamino), and 3-(3-chlorophenylamino) derivatives of 5-amino-1Н-1,2,4-triazole reaches 70–87%. In acid solutions, the synthesized compounds show higher performance than the 3,5-diamino derivative, ensuring up to 92–96% protection. Similar results were obtained in experiments in a salt fog chamber.

Abstract: Reaction of dimethyl N-cyanodithioiminocarbonate and arylamine or alkylamine compounds in the refluxing ethanol solution afforded the according methyl N-substituted-N′-cyanocarbamimidothioates 1–16 in good yields. Compounds 1–16 were characterized by proton nuclear magnetic resonance (1H NMR) and infrared spectroscopies, of which the structures of compounds 1, 2 and 3 (Elgemeie et al. in Acta Cryst E71:104–111, 2015) were established by X-ray crystallography, showing that weak hydrogen-bonding interactions exist in compounds 1–3. Compound 1 crystallizes in the orthorhombic space group Pbca, with a = 6.997(2), b = 7.395(2), c = 36.112(11) ?, and Z = 8. The unit cell of 2 has a monoclinic P21/c symmetry with the cell parameters a = 5.8717(12), b = 4.6598(9), c = 37.799(9) ?, β = 91.126(6)°, and Z = 4. Compound 3 crystallizes in the orthorhombic space group Pbca, with a = 7.123(3), b = 7.374(3), c = 38.538(16) ?, and Z = 8. Graphic Abstract: A series of methyl N-subsituted-N′-cyanocarbamimidothioate compounds were efficiently synthesized via the reaction of arylamine or alkylamine compounds with dimethyl N-cyanodithioiminocarbonate. The structures of compounds 1–3 were characterized by X-Ray crystallography.[Figure not available: see fulltext.]

A new, efficient, catalyst-free, one-pot, three-component method for the synthesis of 2-amino-substituted 7-amino-1,2,4-triazolo[1,5-a][1,3,5]triazines using 3,5-diamino-1,2,4-triazoles, cyanamide, and triethyl orthoformate is developed. The reaction proceeds smoothly under microwave-assisted heating. Advantages of the method include using easily available reagents, short reaction times, and operational simplicity.
