実験手順

210 g (0.838 mol) of 2,4-difluoro-6-trichloromethoxy-1,3,5-triazine were added within 10 minutes to 110 g (0.615 mol) of antimony trifluoride while stirring at 110° C. After addition of 3/4 of 9.38 g (0.0313 mol) of antimony pentachloride, the mixture was heated to 145° C. and stirred for 1 hour. The remaining catalyst was added, and the mixture was stirred for a further 2 hours while a fraction boiling at 95°-105° C. was obtained through a 30 cm packed column: 20 g (11.8% of theory) of 2,4-difluoro-6-trifluoromethoxy-1,3,5-triazine. The residue was distilled without a column to yield 94.8 g (52% of theory) of the title compound of boiling point 125°-130° C.; nD24 =1.4042.
