2-Polyfluoroalkylchromones 5. Nitration and chlorination of 2-trifluoromethylchromones

Abstract:

Electrophilic nitration of 2-trifluoromethylchromone and its 6-and 7-methoxy derivatives affords 6-, 5-, and 8-nitro derivatives, respectively, while 5,7-dimethyl-2-trifluoromethylchromone yields a 6,8-dinitro derivative. Radical chlorination results in 3-chloro derivatives.
