| titleOfInvention | Method of producing nitrozonium salts |
| abstract | The invention relates to methods for producing nitrosone salts of the general formula (NO N A N- , where A N- - BF 4 , CLO 4 , SO 3 F, SIF 6 n n n N = 1-2, which can be used in organic syntheses as active nitrosating and oxidizing reagents, as well as initiators of electrophilic reactions. The purpose of the invention is to expand the nomenclature and increase the yield of nitrozone salts produced while maintaining their high purity. To do this, at 0-15 ° C in the presence of a solvent, the reaction is carried out between nitrogen tetroxide and tertiary ammonium salts of the general formula [ALK 3 NH] N A N- , where ALK is methyl, ethyl, n-butyln n n A N- - BF 4 , CLO 4 , SO 3 F - , SIF 6 , N = 1-2. The solvent is selected from the group methylene chloride, chloroform, concentrated nitric acid, or a mixture thereof. The ammonium salts necessary for the synthesis are obtained by reacting tertiary amines with the corresponding acids. The purity of the nitrosone salts obtained reaches 99.85-99.9%, and the practical yield as compared with the prototype increases by 6-11%. 1 hp f-ly. |
