Acidity continued picolines

Photochlorination of 2-picoline (X-112) at 50 to 150° produces 3-chloro-2-trichloromethylpyridine (X-113) and 3,6-dichloro-2-trichloromethyl-pyridine (X-114). Hydrolysis with concentrated nitric acid gave a 95% yield of the corresponding 2-carboxylic acids. Continued photochlorination affords a perchlorinated trichloromethylpyridine (X-llS), which, after ammonolysis and boiling in sulfuric acid, afforded picloram (X-116). ... [Pg.279]

The reactions of pyridine l-oxide eoa nd picoline l-oxide ci with carboxylic acid anhydrides continue to attract attention, particularly as regards mechanism (see Chapter 6). [Pg.281]
