1.3.5- Triazine-2,4,6-triamines

Beton and co-workers extended the hydrogen bonding approach to two-component systems, generating a number of structures that utilise different molecular motifs.24 26 In the case of perylene tetracarboxylic diimide (PTCDI) co-adsorbed with melamine (1,3,5-triazine-2,4,6-triamine) on a silver-terminated silicon surface, a network is formed in which the straight edges correspond to PTCDI with melamine at the vertices (Figure 11.6). The network shows large-area pores that the authors used to trap heptamers of C6o molecules.

Melamine is characterized by its three amino (-NH2) groups and by its 66.6% nitrogen content. It is known by several different names 1,3,5-triazine-2,4,6-triamine melamine crystal cyanurotriamide 2,4,6-triamino-s-triazine cyanuramide and cyanuric acid amide. Its chemical formula can be written as C3IW or C3N3(NH2)3. Liebig first prepared it in 1834, but it was not until 1937 that it was produced commercially.

Triazine-2,4,6-triamines 38 and 39 with symmetrical and asymmetrical substitution respectively can be obtained under microwave irradiation in solvent-free conditions by reaction of pyrazolylamines with cyanuric chloride 36 and 2-chloro-4,6-diamino-l,3,5-triazine 37 respectively. In the latter case, the procedure can be adapted for the preparation of polymer-supported triazines, with application in supramolecular combinatorial synthesis <05MI649>. 

Triazines are one of the oldest known compound classes in organic chemistry. First reports date back to 1776 when cyanuric acid (l,3,5-triazine-2,4,6-triol 1,3,5-triazine-2,4,6(l//,3//,5f/)-trione) was obtained by the pyrolysis of uric acid.1 The same method was also utilized in 1820 2 however, triazine compounds were probably first prepared in 1704 upon trimerization of cyanide derivatives when the Berlinerblau -complex salt, the first known cyano compound, was discovered.468 Cyanuric chloride was synthesized in 1828 from hydrogen cyanide and chlorine.3 Another method, discovered in 1834, involves treatment of potassium thiocyanate with chlorine. When heated, cyanuric chloride is obtained.4 Melamine (1,3,5-triazine-2,4,6-triamine) was also prepared in 1834 by heating potassium thiocyanate with ammonium chloride.5 Although 2,4,6-substituted 1,3,5-triazine derivatives were identified very early, the unsubstituted parent compound was not synthesized before 1895.6 At that time, however, the isolated compound was assigned to a dimeric species and not to the trimeric hydrogen cyanide. This was finally proven much later."... 

Triazine-2,4,6-triamines (melamines) can be obtained by the trimerization of cyanamides. The parent compound, melamine, was first reported in 1834 as the product from heating a mixture of potassium thiocyanate and ammonium chloride.222 Starting from cyanamidc, the synthesis is achieved either in molten cyanamide above 150 °C,10 or by heating in a high boiling solvent.223...

The formation of salts with melamine (1.3,5-triazine-2,4,6-triamine) is the most extensively studied reaction of this type. In most cases, melamine acts as a monoacidic base and forms salts with mineral acids, e.g. hydrochloric acid, nitric acid or sulfuric acid, inorganic complexes, e.g. hydrogen tetrachloroaurate(III) or dihydrogen hexachloroplatinate(IV) and a large variety of organic acids, e.g. acetic acid, oxalic acid, picric acid or some sulfonic acids.30... 

The 1,3,5-triazine ring of melamine (1,3,5-triazine-2,4,6-triamine, l) is very stable and is cleaved only under very vigorous conditions.7,8 When melamine is heated with potassium carbonate or a mixture of sodium and potassium carbonate at 375 450°C in an aluminum vessel, the corresponding alkali cyanates 2 are formed by ring fission.9 A similar conversion is achieved with potassium hydroxide at about 250 °C.8 10 Thermal decomposition of melamine occurs on heating above 600CC,7 and on reaction with sodium amide and carbon at 760-850°C, alkali cyanides are formed.8...
