2,4-Diamino-1,3,5-triazines have been prepared by reaction of dicyandiamide with nitriles under microwave irradiation, a method that can be considered as a green procedure due to the reduction in the use of solvents during synthesis and purification, the short reaction time and the simplicity of the procedure. The structures have been confirmed in solution by NMR spectroscopy. Variable temperature experiments have been used to calculate the free energy of activation for rotation about the amino-triazine bond. The crystal structures of three 2,4-diamino-6-R-1,3,5-triazine derivatives (3a: R = phenyl, 3i: R = 1-piperidino and 3g: R = 1-phenylpyrazol-3-yl) have been determined by X-ray analysis. The N-H...N interactions change from structure to structure, resulting in a variation from pseudo-honeycomb networks to corrugated rosette layers.

The present invention relates to a cyanoethylmelamine derivatives of the formula I: {wherein 1 to 5 of the substituents X' to X6represent a cyanoethyl group and at least one remaining group represents a C1-20alkyl group, a C2-20alkenyl group (said alkyl or alkenyl group may optionally have an alicyclic group or a phenyl group in its structure), a C5-6cycloalkyl group or a phenyl group, or two of the substituent groups bonded to the same nitrogen atom together may form an alkylene chain having 2 to 7 carbon atoms, and the remaining substituent or substituents represents a hydrogen atom}. The production of cyanoethylmelamine derivatives can be obtained at high yield by reacting N-substituted melamine derivatives with acrylonitrile or reacting mono- or di-halogeno-N-substituted triazine derivative with aminopropionitrile. The compounds of the formula (I) are useful compounds as intermediates for fine chemicals such as agricultural chemicals, medicines, dye stuffs, paints, etc. and as crosslinking intermediates for resins.
