The known method cannot be obtained 3,3'-[bis(1,4-phenylene)]bis-1,3,5-diazinane General formula (1).

The known method (Akhmetov V.R., Yatsina ST and other Synthesis, crystal structure and mutual transformation of new N-aryl-1,3,5-diazinane, 1,3,5-thiadiazines and 1.5-dithia-3,7-diazacyclooctadecane.

The known method cannot be obtained 3,3-[bis(1,4-phenylene)]bis-1,3,5-diazinane General formula (1).

Thus, the literature contains no information about selective receipt of 3,3'-[bis(1,4-phenylene)]bis-1,3,5-diazinane General formula (1).

Features new the way to obtain 3,3'-[bis(1,4-phenylene)]bis-1,3,5-diazinane General formula (1).

The method consists in the interaction of diphenylethylamine General formula H2T-C6H4-R-C6H4-NH2where R=CH2About (diaminodiphenylmethane, diaminodiphenylamine) with N-mpem-butyl-1,3,5-diazinane in argon in the presence of a catalyst Sm(NO3)3·6H2O when the molar ratio differentiatin : N-tert-butyl-1,3,5-diazinon : Sm(NO3)3·6H2O=1:2:(0.03-0.07), preferably 1:2:0.05, at room temperature (~20°C) and atmospheric pressure in the solvent system ethanol-chloroform (1:1, volume) for 2.5-3.5 hours the Yield of 3,3'-[bis(1,4-phenylene)]bis,3,5-diazinane (1) is 50-58%. The reaction proceeds according to the scheme:

3,3'-[Bis(1,4-phenylene)]bis-1,3,5-diazinane General formula (1) are formed only with the participation of diphenylethylamine and N-tert-butyl-1,3,5-diazinane under the action of catalyst Sm(NO3)3·6H2O. In the presence of other diamines (for example, alkeneamine) target products (1) are not formed.

Conducting the reaction in the presence of a catalyst Sm(NO3)3·6H2O more than 7 mol. % towards differentiatio not lead to a significant increase of the yield of the target product (1). Use in the reaction of the catalyst Sm(NO3)3·6H2O less than 3 mol. % reduces output (1), which is associated with reduced catalytically act the main centres in the reaction mass. The reaction was carried out at room temperature ~20°C. At a higher temperature (e.g. 60°C) decreases the selectivity of the reaction and increase the energy consumption, at a lower temperature (for example, 0°C) decreases the reaction rate. The experiments were carried out in the solvent system ethanol-chloroform (1:1, volume), as well dissolve the original reactants.

Significant differences of the proposed method.

In the known method, the reaction goes in the boiling solvent at a temperature of 60-70°C for 24 h the Known method does not allow you to obtain an individual 3,3'-[bis(1,4-phenylene)]bis-1,3,5-diazinane General formula (1).

In the proposed method, the reaction proceeds with the participation of as initial reagents N-tert-butyl-1,3,5-diazinane and diphenylethylamine (diaminodiphenylmethane, diaminodiphenylamine) under the action of catalyst Sm(NO3)3·6H2O at a temperature of 20°C. In contrast to the known proposed method allows you to obtain an individual 3,3'-[bis(1,4-phenylene)]bis-1,3,5-diazinane General formula (1), the synthesis of which are not described in literature.

The method is illustrated by the following examples:

EXAMPLE 1. In the vessel Slanka mounted on a magnetic stirrer, an argon atmosphere was placed 0.198 g (1 mmol) of diaminodiphenylmethane in 5 ml of ethanol, 0.022 g (0.05 mmol) Sm(NO3)3·6H2O, and then added dropwise 0.354 g (2 mmol) N-tert-butyl-1,3,-diazinane in 5 ml of chloroform. The reaction mixture was stirred at room temperature (~20°C) for 3 hours, add 2 ml of distilled water and extracted with chloroform. Chloroform fraction chromatographic on a column with SiO2and produce 3,3'-[methylene-bis-(1,4-phenylene)]bis-1,3,5-diazinon with the release of 54%. Other examples of the method are given in table. 1.
