Preparation of 6-trifluoromethyl-1,3,5-triazines I (R¹ = H, R¹, R² = C-organic radicals) by reacting salts of an N-amidino-S-alkylisothiourea II (R³ = C₁-C₁₀) with trifluoroacetic acid derivatives III and strong base IV to 6-trifluoromethyl-1,3,5-triazines V and reaction of process products V in the presence of a base with alcohols VII R²-OH VII. n n n Triazines I are valuable intermediates for crop protection products. |
