| titleOfInvention | Preparation of substituted 1,2-dihydro-1,3,5-triazine |
| abstract | PURPOSE: To obtain the title substance useful as an intermediate for pesticides, medicines, and high polymers in one step in high yield without using powerful agents, by reacting a nitrile and an aldehyde or ketone in the presence of ammonia and an alcohol under pressure. n CONSTITUTION: One mole of a nitrile of the formula R 1 CN (R 1 is aryl, aralkyl, heterocyclic group, etc.) is reacted with 2W10mol of an aldehyde of the formula R 2 CHO (R 2 is H, alkyl, aryl, aralkyl, heterocyclic group, etc.) or 1mol of a ketone of the formula R 3 COR 4 (R 3 and R 4 are alkyl groups) in the presence of ammonia and 0.1W10mol of an alcohol under pressure to give the title substance of formula I or II. The amount of ammonia is 1.1W10mol per mole of the aldehyde or ketone, and the reaction pressure is 1,000W9,000kg/cm 2 . n COPYRIGHT: (C)1980,JPO&Japio |
