We report here a comparative theoretical and experimental study of four triazine-based hydrazone derivatives. The hydrazones are synthesized by a three step process from commercially available benzil and thiosemicarbazide. The structures of all compounds were determined by using the UV-Vis., FT-IR, NMR (1H and 13C) spectroscopic techniques and finally confirmed unequivocally by single crystal X...

This study describes the synthesis of triazine-based dehydrocondensing reagents substituted by amido substituents and demonstrates their efficiency for dehydrocondensing reactions in MeOH and THF. N-Phenylbenzamido-substituted chlorotriazine is readily converted to a stable, non-hygroscopic triazinylammonium-based dehydrocondensing reagent that is superior to 4-(4,6-dimethoxy-1,3,5-triazin-2-yl...

Bifunctional ureido-s-triazines provided with penta(ethylene oxide) side chains are able to self assemble in water, leading to helical columns via cooperative stacking of the hydrogen-bonded pairs (DADA array). Monofunctional ureido-s-triazines do not form such helical architectures. The presence of a linker, covalently connecting the two ureido-s-triazine units, is essential as it generates a ...

There is increasing concern that certain chemicals in the environment can cause endocrine disruption in exposed humans and wildlife. Investigations of potential effects on endocrine function have been limited mainly to interactions with hormone receptors. A need exists for the development of alternate in vitro methods to evaluate chemicals for their potential to disturb various endocrine functi...

Mixtures of simazine, atrazine, ametryne, prometryne, deethylsimazine, deethylatrazine, hydroxysimazine, hydoxyatrazine, hydoxyprometryne, N-ethyland N-isopropylammeline, N-ethyland N-isopropylammelide, melamine, ammeline, ammelide, and cyanuric acid in aqueous solution were separated and determined in a single analysis with a detection limit of 30-400 pmol. The s-triazines were detected by a U...

The asymmetric unit of the title compound, C(5)H(11)N(5)O(2), contains two independent mol-ecules. The two triazine rings adopt envelope conformations. Intra-molecular C-H⋯N and N-H⋯O hydrogen bonds result in the formation of two five- and two six-membered rings which are nearly planar; in addition, they are also nearly coplanar. In the crystal structure, inter-molecular N-H⋯N, C-H⋯N and C-H⋯O ...

In the title compound, C(9)H(9)N(5)S, the pyridyl and triazine rings make a dihedral angle of 4.8 (2)°. In the crystal, adjacent mol-ecules are bridged by an N-H⋯N hydrogen bond, forming a helical chain running along the b axis.

Herein, we report the targeted synthesis and solid state assembly of a novel triazine-based [4+6] organic molecular cage. The tetrahedral cage features a large cavity (∼2070 Å(3)), and after desolvation, the resultant material exhibits a high Brunauer-Emmett-Teller surface area of 1181 m(2) g(-1) and also features selective adsorption of CO2 over N2.

The product of an episulfonium ion-mediated cyclotrimerisation, previously reported as being a 15-membered ring trilactam, has now been shown to be a 1,3,5-triazine. Smaller medium-ring bilactams have, however, been synthesised from linear precursors using the sulfur-based methodology.
