Method for synthesizing 2, 4, 6-trisubstituted 1, 3, 5-triazine compound from aromatic aldehyde and ammonium iodide

The invention discloses a method for synthesizing a 2, 4, 6-trisubstituted 1, 3, 5-triazine compound from aromatic aldehyde and ammonium iodide, and belongs to the field of organic synthesis. According to the method, aromatic aldehyde and ammonium iodide undergo a one-pot reaction under the catalytic action of a ferric salt, so that the 2, 4, 6-trisubstituted 1, 3, 5-triazine compound is obtained.According to the present invention, the small molecule aryl aldehyde raw material and the iron salt catalyst are used, such that the cost is low, the reaction conditions are mild, the symmetric 2, 4,6-trisubstituted 1, 3, 5-triazine compound can be highly selectively obtained, and the brand-new synthesis idea is provided for the triazine ring construction.

Atom-efficient synthesis of 2,4,6-trisubstituted 1,3,5-triazinesviaFe-catalyzed cyclization of aldehydes with NH4I as the sole nitrogen source

An atom-efficient, straightforward method for the synthesis of 2,4,6-triaryl-1,3,5-triazinesviairon-catalyzed cyclization of aldehydes with NH4I as the sole nitrogen source is demonstrated. This strategy works smoothly under air atmosphere, and affords symmetrical 2,4,6-trisubstituted and unsymmetrical 1,3,5-triazines with yields from 18% to 72%. Compared to other methods, the present protocol provides a straightforward and atom-efficient approach to 2,4,6-trisubstituted 1,3,5-triazines using an inexpensive, easily available ammonium salt as the sole nitrogen source. Research into the preliminary mechanism indicates thatN-benzylidenebenzimidamides are involved in this cyclization reaction.

Palladium nanoparticles immobilized on nano-silica triazine dendritic polymer (Pdnp-nSTDP): An efficient and reusable catalyst for suzuki-miyaura cross-coupling and heck reactions

A new catalyst based on palladium nanoparticles immobilized on nano-silica triazine dendritic polymer (Pdnp-nSTDP) was synthesized and characterized by FT-IR spectroscopy, thermogravimetric analysis, field emission scanning electron microscopy, energy dispersive X-ray, transmission electron microscopy and elemental analysis. The size of the palladium nanoparticles was determined to be 3.1±0.5 nm. This catalytic system showed high activity in the Suzuki-Miyaura cross-coupling of aryl iodides, bromides and chlorides with arylboronic acids and also in the Heck reaction of these aryl halides with styrenes. These reactions were best performed in a dimethylformamide (DMF)/water mixture (1:3) in the presence of only 0.006 mol% and 0.01 mol% of the catalyst, respectively, under conventional conditions and microwave irradiation to afford the desired coupling products in high yields. The Pdnp-nSTDP was also used as an efficient catalyst for the preparation of a series of star- and banana-shaped compounds with a benzene, pyridine, pyrimidine or 1,3,5-triazine unit as the central core. Moreover, the catalyst could be recovered easily and reused several times without any considerable loss of its catalytic activity. Copyright

Oxidation of Aromatic Compounds. V. Oxidation of Substituted Benzonitriles and 2,4,6-Triaryl-1,3,5-Triazines in System HSO3F-PbO2

Low-temperature oxidation of substituted benzonitriles by the system HSO3F-PbO2 proceeds with intermediate formation of cation-radicals and leads to substitution of hydrogen atoms of the methyl group or benzene ring. This reaction provides a route for preparation of chloromethylsubstituted benzonitriles, diarylmethanes, diaryls, arylfluorosulfonates and substituted benzamides with cyano groups. In the case of methyl derivatives of 2,4,6-triphenyl-1,3,5-triazine substitution of the first and then the second hydrogen atom of the same methyl group transforms it into hydroxy or chloromethyl group, or into the aldehyde function.

Lanthanide(III) Ion Catalyzed Reaction of Ammonia and Nitriles: Synthesis of 2,4,6-Trisubstituted-s-triazines

Lanthanum and yttrium trifluoromethanesulfonates at 1 mole percent concentration, have been found to catalyze a reaction between ammonia and aromatic nitriles to yield symmetrically substituted 2,4,6-triaryl-s-triazines.The generally high yields and relatively mild reaction conditions of this procedure suggest it as an alternative to other aromatic nitrile cyclotrimerization reactions.Of the aliphatic nitriles studied, acetonitrile and cyclopropanecarbonitrile gave good yields of triazine, propionitrile and butyronitrile gave significantly reduced yields of triazines 3b and3c respectively.Rearrangement of 3a and 3b to alkylated-4-aminopyrimidines was observed.

Triflic acid catalyzed aroylation of arenes with aromatic nitriles

In the presence of triflic acid, the reaction of different aromatic nitriles with arenes under a variety of conditions was examined.In addition to the normal reaction products (the s-triazines), aroylation of the arene to produce diaryl ketones in 20 to 50 percent yield was observed.Possible mechanism for the reaction was proposed.
