Tris -s-triazine

Trichloroborazene reacts with bis(trimethylsilyl)carbodiimide to form non-oxide B/C7N gels. These gels consist of three-dimensional polymeric networks linked by carbodiimide groups." Similar polycarbodiimide hydrid gels are prepared from tris-s-triazines and bis(trimethylsilyl)carbodiimide." The viscoelastic properties of a gel system based on methyltrichlorosilane and bis(trimethylsilyl)carbodiimide have been reported." ...

The GeO region is GeO and N-doped graphene.

A cyameluric high polymer 92 has been synthesized by two step solid-polymerization of melon (a linear form of the decamer of 2,5,8-triamino-tris-s-triazine) at about 700 <01M119>. New derivatives of fused fluoroquinolones bearing five aromatic rings, including structures 93 and 94, have been synthesized <01 JFC(110)25>.

Perhaps the most firmly based report for the formation of an azete involves flash pyrolysis of tris(dimethylamino)triazine (303). This gave a red pyrolysate believed to contain the highly stabilized azete (304) on the basis of spectroscopic data. The putative azete decomposed only slowly at room temperature, but all attempts to trap it failed (73AG(E)847). Flash pyrolysis of other 1,2,3-triazines gives only acetylenes and nitriles and it is not possible to tell whether these are formed by direct <,2-l-<,2-l-<,2 fragmentation of the triazine or by prior extrusion of nitrogen and collapse to an azete (81JCR(S)162). 

Dichloro-s-triazine and its 6-alkyl analogs are as easily hydrolyzed by water as trichloro-s-triazine and, on suspension in aqueous ammonia (25°, 16 hr), the first is diaminated in good yield. 2,4-Bistrichloromethyl-6-methyl- and -6-phenyl-s-triazines (321) require a special procedure for mono-alkoxylation (0-20°, 16 hr, alcoholic triethylamine) disubstitution occurs at reflux temperature (8 hr). Aqueous triethylamine (100°, 3 hr) causes complete hydroxy-lation of 2,4,6-tris-trichloromethyl-s-triazine which can be mono-substituted with ammonia, methylamine, or phenoxide ion at 20°. 

Trichloro-s-triazine also reacts readily with carbon or phosphorus nucleophiles. Diethylmalonate anion forms a mono-derivative under mild conditions and the tri-substitution product (327) under vigorous conditions with excess nucleophile. Nucleophilic attack by the 7r-electrons of ketene diethylacetal to give 254 and of dimethylaniline to give 253 has been mentioned earlier. Two... 

Tris-methylthio-s-triazine undergoes similar displacement with methanolic methoxide. Its methylthio groups are substituted with sodium sulfide and with ammonia. Methylthio and carboxymethylthio substituents are readily hydrolyzed by dilute acid. ...

Formaldehyde release biocides are perhaps the most commonly used biocides in metalworking fluids. One of die best know examples of this chemistry is hexahedron -l,3,5-tris(2-hydroxyethyl)-s-triazine, (see Figure 2). 

The addition of copper to a boiling solution of benzenesulphonyl azide in methanol gave benzenesulphonamide 18 (80%) as the major product together with minor amounts of methylenebis(benzenesulphon-amide) 22 and 1,3,5-tris (benzenesulphonyl) hexahydro-s-triazine 23, resulting from condensation of 18 with the formaldehyde formed in the reaction 33>. Cuprous chloride was even more effective, but cuprous... 

The tris(acryloyl) derivative (R is CH = CH2) was subsequently developed as a fixing agent for use with the Basazol(BASF) dyes in the printing of cellulosic fibres, in conjunction with urea as hydrotrope [444]. It has also been shown [445] that aftertreatment with 1,3,5-tris(acryloyl)hexahydro-s-triazine or the tris ((3-chloropropionyl) derivative improves the wet... 

Pelizzetti et al. (1990) investigated the photocatalytic degradation of atrazine in solution in the presence of suspended titanium dioxide as a catalyst under simulated sunlight. Degradation was rapid but mineralization did not occur. Intermediate compounds included 6-hydroxy-A/-ethyl-/V -(l-methylethyl)-5 triazine-2,4-diamine, 2,4-diamino-6-chloro-A/-(l-methylethyl)-5-triazine, 2,4-di-amino-6-chloro-/V-ethyl-5-triazine, 2,4-diamino-6-chloro-5-triazine, 2,4-diamino-6-hydroxy-5-tri-azine, 2-amino-4,6-dihydroxy-5-triazine, 2-amino-4-hydroxy-6-chloro-5-triazine, 2,4-dihydroxy-6-chloro-s-triazine, 6-chloro-/V-acetyl-/V -(l-methylethyl)-5-triazine-2,4-diamine, and cyanuric acid as the final product.
