| titleOfInvention | 2-Isocyanatosulfonylbenzoic acid esters and preparation thereof |
| abstract | 2-Isocyanatosulfonylbenzoic acid esters of the general formulan n wherein R is selected from various hydrocarbyl and substituted hydrocarbyl groups; R 2 is H, Cl, Br, F, C 1 -C 3 alkyl, -NO 2 , -OCH 3 , -SCH 3 , CF 3 , SO 2 CH 3 , N(CH 3 ) 2 , CN, or 4-N=C=O; and R 3 is H, Cl, Br or CH 3 with the proviso that when R is other than C 3 -C 10 alkynyl, then R 2 must be 4-NCO. are novel intermediates for the preparation of herbicidal ureas. The isocyanates may be prepared e.g. by reacting a corresponding 2-sulfamoylbenzoate ester of general formulan wherein R 2 ' is NH 2 or R 2 as defined above, with a hydrocarbyl isocyanate and phosgene in the presence of a catalytic amount of a tertiary amine base and an inert solvent. |
