The relative and absolute configurations of diepoxydicarbazoles involving the 2,6-dioxa-4,8-diazaadamantane system were determined in the course of a study on indole and indole alkaloids.242 Water-soluble azo, anthraquinone, and phthalocyanine dyes which are substituted by a 4-chloro-s-triazin-2-ylamino group can be quaternized with a l-aza-3-methyl-4,6,10-trioxa-adamantane unit in aqueous medium at 40 50"C.243 Dyes mixed with...

The H+ and NH forms of homoionic montmorillonite promote the hydrolysis of chloro-s-triazines to the hydroxy analogs (hydroxy-s-triazines) (73). Apparently, the surface acidity of these clays was extremely high, since no degradation was observed in control experiments conducted at pH 3.5 in homogeneous aqueous solution. Russell et al. (73) suggested that the hydroxy-s-triazine products were stabilized in the protonated form at the silicate surface. The IR spectra of these surface complexes agreed with the spectra obtained in 6N HC1, and it was inferred that the pH at the clay surface was 3 to 4 units lower than that measured in suspension.

There has been a study of the mechanism of the activation of carboxylic acids to peptide formation by chloro-s -triazines in combination with tertiary amines. The first step, exemplified in Scheme 2 by the reaction of 2-chloro-4,6-disubstituted-l,3,5-triazines (18) with A -methylmorpholine, is formation of a quaternary triazinylammonium salt (20). Here there is NMR evidence for the formation at —50°C of the intermediate (19), showing that the substitution involves the two-step SnAt mechanism rather than a synchronous pathway. The subsequent reaction of (20) with a carboxylic acid yields the 2-acyloxy derivative (21), which carries an excellent leaving group for the amide-forming step. ...

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.

Hydrolysis of triazine herbicides, for example, describes humic-induced transformation of toxic organic molecules. The catalytic effects of the chloro-s-triazine herbicides on dechloro-hydroxylation were determined by Armstrong et al. (1967).
