| titleOfInvention | Process for preparing 5-(2-chloro-4-trifluoromethylphenoxy)-2-nitro-N-alkanesulphonyl benzamides from a benzoic acid derivative and intermediates |
| abstract | Preparation of a compound of the following formula (I): ##STR1## wherein R 1 is alkyl of 1 to 12 carbons, from the compound of the following formula (II): ##STR2## by the steps of coupling (II) with 3,4-dichlorobenzotrifluoride; reacting the --NH 2 and COOH groups with a COX 2 compound, X being a leaving group, to produce a heterocycle; opening the heterocycle with an alkanesulphonamide; and oxidizing the resultant --NH 2 group to an --NO 2 to yield a compound of formula (I). Novel intermediates are also described. Compounds of formula (I) are useful as selective pre- and post-emergent herbicides. |
