| titleOfInvention | PROCESS FOR PREPARING 2-ACYL-3-TRICHLOROMETHYL-2-AZANORBORN-5-ENENE |
| abstract | The invention relates to a process for the preparation of 2-acyl-3-trichloromethyl-2-azanorborn-5-enes 1, wherein the azomethines 3 are not isolated, but are reacted immediately after formation with 4. This eliminates a complex step associated with yield losses. By addition of traces of hydroquinone to the reaction mixture as a stabilizer as well as by anaerobic procedure, side reactions of the azomethines 3 are minimized by radical processes, thereby increasing the yield. The addition of 0.1 mol% of freshly sublimed aluminum chloride with respect to 2 leads to a further increase in yield. The azanorbornene derivatives 1 are of interest as crop protection and pest control agents or as starting materials for their synthesis. In addition, these derivatives are starting materials for pharmacologically interesting compounds. |
