| titleOfInvention | Substituted 2-halo-4,5-dicyano-imidazoles and their preparations |
| abstract | 1396826 Substituted 2-halo-4,5-dicyanoimidazoles E I DU PONT DE NEMOURS & CO 6 April 1973 [7 April 1972] 16610/73 Heading C2C The invention comprises compounds of formula where R contains up to 10 carbon atoms and is an alkyl, aryl, aralkyl, fluoro(oxaalkyl), haloalkyl or aryl(haloalkyl) group and X is F, Cl, Br or I, with the proviso that when X is I, R is only alkyl, aralkyl, fluoro(oxaalkyl) or haloalkyl, halo being F, Cl or Br. These compounds are prepared by reacting in the liquid phase at 50- 140 C. 2 - diazo - 4,5 - dicyano - 2H - imidazole with a compound of formula RX, where R and X are as defined above. When RX is chloro- or bromobenzene, a halonium compound of formula was detected in the reaction mixture; in the case of bromobenzene the halonium compound was found to rearrange to give 1-phenyl-2- bromo-4,5-dicyanoimidazole. With reactants RX containing C-H bonds, which may be written R<SP>1</SP>H, 4,5-dicyanoimidazoles substituted by R<SP>1</SP> in the 2 position are obtained as byproducts. In the examples, R is ethyl, various haloalkyl groups, phenyl, phenyl difluoromethyl and 2H-5-(trifluoromethyl)-perfluoro-3,6-dioxa- 2-nonyl. |
