Versuchsvorschrift

As another example, benzotrifluoride by nitration gives 3-nitrobenzotrifluoride which in turn by reduction gives 3-aminobenzotrifluoride. The latter can be reacted with phosgene to yield the 3-isocyanatobenzotrifluoride. In the subsequent reaction of the isocyanate with dimethylamine the 1-(3-trifluoromethylphenyl)-3-dimethyl-urea is obtained which is an important herbicide (DE-AS (German Examined Specification) No. 1206201).
