| titleOfInvention | Herbicidal dichloro trifluoromethybenzoic acids and - their salts |
| abstract | Herbicidal dichloro trifluoromethybenzoic acids and their salts. M5-. New cpds. of formula: (in which when the C1 is ortho to the CF3, the COOH is meta to the CF3 and adjacent to each of the C1 atoms) are prepd. by (a) reacting a cpd. of formula (II): (where the position of the Li atom is as described for COOH in I) with CO2 in an inert solvnt, or (b) by oxidising a cpd. of formula: pref. in the presence of Cu+, Co+ or Fe2+. Uses of (I) are as selective herbicides at an applicaton rate of 2-10 kg/Ha and as total herbicides at 10-30 kg./Ha. (II) are intermediates for (I). Preparation of (II) is by reaction of lithium butyl with the appropriate dichloro-trifluoromethylbenzene. |
