| titleOfInvention | PROCESS FOR PRODUCING SUBSTITUTED 2-AMINO-2H-THIOPYRANEES |
| abstract | The invention relates to the field of organic synthetic chemistry and has a method to the goal, with the 2-dialkylamino-2H-thiopyrans of the formula III (IPKC 07 D) can be prepared, which are sufficiently stabilized by suitable substituents and thus isolable in substance , The invention has for its object to use as starting materials suitable substituted thiopyrylium salts and dialkylamines. The object is achieved in accordance with the invention by using thiopyrylium salts of the formula I in which R is 1, R is highly reactive 3 and R 5 is aryl, R is high or R is hydrogen, alkyl or aryl radicals and X is any anion, with secondary amines of the formula II in which R is 6 and R 7 is identical or different or linked alkyl radicals. Compounds of formula III are e.g. usable as dye-forming agent. |
