Process for preparation of 6-fluoro-anthranilic acid nitrile or 6-fluoro-anthranilic acid and 6-fluoro-anthranilic acid nitrile

摘要

Fluorinated anthranilic acid and anthranilonitrile, and a novel process for their preparation by reacting 2,6-difluorobenzonitrile with ammonia and, if the acid is required, hydrolyzing the resulting 6-fluoroanthranilonitrile with a basic compound. The two novel end products are valuable intermediates for the preparation of compounds which are useful for controlling various animal pests and plant pests.
