| titleOfInvention | Method for producing 4,6-disubstituted 2-isocyanatopyrimidines and to their use as intermediate products for active ingredient syntheses |
| abstract | The invention relates to isocyanates of formula (I), wherein X and Y as shown in formula (I) are defined according to Claim No. 1, which can be produced by reacting a compound of formula (II) or the salts thereof, wherein X and Y are defined as in formula (I), with 1 to 6 mol of phosgene per 1 mol of the compound of formula (II), in the presence of 2 to 3.5 mole equivalents of a base per mol of the compound of formula (II) and in the presence of an aprotic organic solvent. The reaction is carried out at a reaction temperature ranging from -30 to +60 DEG C for the compound of formula (I). The compounds (I) can be converted into addition products such as carbamates, ureas, sulfonylureas, and corresponding products, e.g. herbicidal sulfonylureas, by reacting them with nucleophiles. |
