  • New 6-cyanomethyl-1,3,5-triazine derivatives 4 containing amino, n-propylamino, isopropylamino and anilino groups at 2-and 4-position on the 6-cyanomethyl-1,3,5-triazine ring were prepared from 6-chloro-l,3,5-triazine derivatives 2' and 3 with tert-butyl cyanoacetate. The derivatives of 6-chloro-l,3,5-triazine 2' and 3 containing amino, n-propylamino, isopropylamino and anilino groups at 2- and 4-position on the 6-chloro-1,3,5-triazine ring were prepared from 2,4,6-trichloro-1,3,5-triazine as well as 4,6-dichloro-1,3,5-triazine derivatives 2 with amine derivatives.

  • The versatile, hitherto unreported 3-(4-(2-phenyldiazenyl)-2-oxo-2H-chromen-3-yl)-3-oxopropanenitrile 3 was prepared by two convenient routes: either by the reaction of ethyl 4-(2-phenyldiazenyl)-2-oxo-2H-chromen-3-carboxylate 2 with acetonitrile in the presence of sodium hydride or by treatment of 4-(2-phenyldiazenyl)-3-(2-bromoacetyl)-2H-chromen-2- one 5 with potassium cyanide. Reaction of 3 with heterocyclic diazonium salts 6, 7, 14 and 17 furnished the corresponding hydrazones 8, 9, 15 and 18. The latter hydrazones underwent intramolecular cyclization into the corresponding pyrazolo[5,1- c]-1,2,4-triazine 10, 1,2,4-triazolo[5,1-c]-1,2,4-triazine 11, 1,2,4-triazino[4,3-b]indazole 16 and imidazo[2,1-c]-1,2,4-triazine 19 derivatives, respectively upon refluxing in pyridine.

  • New 4,4'-[6-(o-carboranylalkoxy)-1,3,5-triazine-2,4-diyl]dimorpholine derivatives have been prepared by reacting 4,4'-[6-(alkynyloxy)-1,3,5-triazine-2,4-diyl]dimorpholines with decaborane and N,N-dimethylaniline as base. The intermediate compounds, 4,4'-[6-(alkynyloxy)-1,3,5-triazine-2,4-diyl]dimorpholines, have been prepared by reacting 4,4'-[6-chloro-1,3,5-triazine-2,4-diyl]dimorpholines with prop-2-yn-1-ol, but-3-yn-1-ol, and pet-4-yn-1-ol, and potassium tert-butoxide (t-BuOK) as base. The structure of these compounds has been confirmed by IR, $^1H$, $^{11}B$, and $^{13}C$ NMR and X-ray crystallographic studies.

  • Hyperbranched poly(ether sulfone) analogs with the 1,3,5-s-triazine moiety were prepared by the direct polymerization of AB$_2$type monomer, 2,4-bis(4-hydroxyphenyl)-6-(4-(4-(4-fluorobenzenesulfonyl)phenoxy)phenyl)-1,3,5-s-triazine (3). The selective reactivity of three chlorine atoms on cyanuric chloride toward nucleophiles provides an efficient route for the systematic synthesis of AB$_2$type triazine monomers and their hyperbranched polymers. The triazine rings influenced the structural and material characteristics of these hyperbranched polymers. The hyperbranched poly(ether sulfone) analog4 showed a glass transition at 295$^{\circ}C$. and was soluble in THF, 1,4-dioxane, and DMSO. An excellent thermal stability of polymer 4 was exhibited by a TGA analysis, which showed that 5% weight loss occurred at 480$^{\circ}C$.

  • Poly(triazine bissulfide)s were synthesized from 6-dibutylamino-1,3,5-triazine-2,4-dithiol with bis(4-chloro-3-nitrophenyl)sulfone in the presence of the phase transfer catalyst, and from m-dibromide xylene and p-dibromide xylene with 6-dibutylamino-1,3,5-triazine-2,4-dithiol in the presence of cetyltrimethyl ammonium bromide at $70^{\circ}C$ for 24h. We could acquire the good results about solubility, thermal property, and molecular weight to make cast film. These results are important as base for the synthesis of functionalization polymer material being optical plastic material. The maximum algebra viscosity was 0.57~1.40dl/g at the temperature more than $50{\sim}60^{\circ}C$.

  • We had reported that s-triazine can readily be converted into the corresponding 5-substituted pyrimide. In order to develop new synthetic method of 5-fluorouracil, we tried to replace eliminating fragment, 1, 3-dimethylurea, by fluoroacetamide, which was expected to undergo nucleophilic attack by proton extraction of both .alpha.-hydrogen and aminohydrogen by lithium diisopropylamide (LDA). We found that 5-fluorouracil could be transformed from s-triazine under strong base condition like LDA as well as other 5-substituted pyrimidines.

  • In this work, the key intermediate, 4-amino-4'-(2-amino-4-anilino-1,3,5-triazine-6-yl)-aminostilbene-2,2'-disulfonic acid, was prepared from 4-(2-amino-4-anilino-1,3,5-triazine-6-yl)amino-4'-nitrostilbene-2,2'-disulfonate by using Tin(II) chloride as the reducing agent. Using this intermediate, nineteen new asymmetrically substituted bistriazinylstilbene fluorescent brightening agents were synthesized. Chemical structures of the obtained compounds 5a-s were analyzed by proton NMR spectrum. The physical properties of the new compounds 5a-s were characterized by fastness test and whiteness measurement test and the obtained data were compared to measurements obtained from CI 86.
