Green synthesis and self-association of 2,4-diamino-1,3,5-triazine derivatives

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.

PCT No. PCT/JP96/03762 Sec. 371 Date Jun. 22, 1998 Sec. 102(e) Date Jun. 22, 1998 PCT Filed Dec. 24, 1996 PCT Pub. No. WO97/24338 PCT Pub. Date Jul. 10, 1997A method for modifying 1,3,5-triazine derivatives characterized by heating and reacting a 1,3,5-triazine derivatives having at least one amino or mono-substituted amino group on a carbon atom or atoms on its ring with an alcohol in the presence of a metal catalyst and a hydrogen atom to introduce an alkyl group or an alkenyl group into each amino or mono-substituted amino group; another method for modifying 1,3,5-triazine derivatives characterized by heating and reacting a 1,3,5-triazine derivatives having at least one amino or mono-substituted amino group on a carbon atom or atoms on its ring with a dihydric alcohol in the presence of a metal catalyst and a hydrogen atom to introduce an alkyl group having a hydroxyl group into each amino or mono-substituted amino group; and 1,3,5-triazine derivatives obtained by the methods. The various modified sustituted 1,3,5-triazine derivatives thus produced are generally obtained as a mixture. These derivatives can be isolated as compounds having high-purity by a normal separation method for organic compounds, and the compounds are usable in the various applications mentioned in the specification.

CYANOETHYLMELAMINE DERIVATIVES AND PROCESS FOR PRODUCING THE SAME

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.
