Abstract
NEW MATERIAL:2-Cyano-3-halogeno-5-trifluoromethylpyridine of forula I (Hal is halogen).
EXAMPLE: 2-Cyano-3-chloro-trifluoromethylpyridine.
USE: Intermediate of pharmaceuticals, pesticides, dyes, etc., or intermediate of organophosphorus compounds such as an imidoyl phosphoric acid ester which is an agent for controlling noxious life.
PROCESS: The compound of formula I is prepared by cyanizing 2-bromo-3-halogeno- 5-trifluoromethylpyridine of formula II with a cyanizing agent such as cuprous cyanide, KCN, etc., pref. in a polar aprotic solvent such as dimethylformamide, at 100W130°C for 10W30min.
