Condensed 1,3,5‐triazines: 1,3,4‐Thiadiazolo[3,2‐a]‐1,3,5‐triazines and isoxazolo[2,3‐a]‐1,3,5‐triazines

Journal of Heterocyclic Chemistry, 1987
AbstractA convenient route is reported for the synthesis of substituted 1,3,4‐thiadiazolo[3,2‐a]‐1,3,5‐triazine‐5,7‐diones and isoxazolo[2,3‐a]‐1,3,5‐triazines. Condensation of the appropriately substituted 2‐amino‐1,3,4‐thiadiazole and 3‐aminoisoxazole with phenoxycarbonyl isocyanate provides the desired target compounds in fair yield.

1,3,5-Triazines. Part X. Complexes of 2,4,6-trisdimethylamino-1,3,5-triazine

J. Chem. Soc. A, 1969
Exocyclic dimethylamino-groups produce a drift of electrons towards the 1,3,5-triazing ring. 2,4,6-Trisdimethylamino-1,3,5-triazine behaves as an electron-donor towards protons, boron trifluoride, and aromatic π-electron-acceptors. A range of complexes of trisdimethylaminotriazine has been characterised.

Azo‐1,3,5‐triazines

Journal of Heterocyclic Chemistry, 1976
AbstractThe synthesis of variously substituted bis‐triazinylhydrazines and their subsequent oxidation preferably with chlorine in a two‐phase system to azo‐1,3,5‐triazines starting from cyanuric chloride is reported. Reaction of ethoxycarbonylhydrazine with cyanuric chloride followed by oxidation gave access to mono‐ and bis‐ethoxycarbonyl‐1,3,5 ...

Regioselective synthesis of imidazo[1,2-a][1,3,5]triazines and 3,4-dihydroimidazo[1,2-a][1,3,5]triazines from [1,3,5]triazin-2,4-diamines

Tetrahedron, 2013
Abstract An efficient and practical procedure was developed to prepare novel imidazo[1,2-a][1,3,5]triazines and 3,4-dihydroimidazo[1,2-a][1,3,5]triazines with a good regioselectivity and high yields, starting from dicyandiamide and the corresponding arylamines. Mechanistic studies for the subsequent cyclocondensation with chloroacetaldehyde support a

Derivatives of 2,4-dimethoxy-1,3,5-triazine

Acta Crystallographica Section C Crystal Structure Communications, 2003
The crystal structure of three derivatives of 2,4-dimethoxy-1,3,5-triazine are described. In 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)morpholine, C(9)H(14)N(4)O(3), the morpholine moiety adopts a chair conformation, and the dimethoxytriazine molecule adopts a butterfly conformation with respect to the two methoxy groups.

Trisubstituted 1,3,5-Triazines. 6. Synthesis of 2,4,6-Tris(acetonyl)-1,3,5-triazine

Chemistry of Heterocyclic Compounds, 2003
Acylation of 2,4,6-tris(tert-butoxycarbonylmethyl)-1,3,5-triazine with acetic anhydride in the presence of lithium hydride with subsequent removal of the tert-butoxycarbonyl groups with trifluoroacetic acid leads to 2,4,6-tris(acetonyl)-1,3,5-triazine, the cyclic analog of α-cyanoacetone.

Study on the 1,3,5-triazine gamma-radiolysis

Journal of Radioanalytical and Nuclear Chemistry, 2008
Triazines are a class of molecules which have been found in meteorites such as Orgueil meteorite. Despite their poor resistance to UV radiation, these molecules survived millions of years inside a meteorite. The present work is dedicated to the examination of the radiation resistance of the simplest sym-triazine: 1,3,5-triazine.
