PREPARATION OF DERIVATIVES OF 6-TRIFLUOROMETHYL-1,3,5-TRIAZINE

摘要

6-Trifluoromethyl-1,3,5- triazines I where R 1 is H and R 1 and R 2 are each a C-organic radical, are prepared by reacting a salt of an N-amidino-S-alkyl- isothiourea II where R 3 is a C-organic radical of 1 to 10 carbon atoms, with a trifluoroacetic acid derivative III and a strong base IV to give a 6-trifluoromethyl-1,3,5-triazine V and reacting the product V in the presence of a base with an alcohol VII R 2-OH VII. The triazines I are useful intermediates for crop protection agents.
