| titleOfInvention | Process for the preparation of beta-chloroethylsulfonylaryl isocyanates |
| abstract | Process for the preparation of β-chloroethylsulfonylaryl isocyanates of the formula (1) n n Cl--H.sub.2 C--H.sub.2 C--O.sub.2 S--A--NCO (1) n n wherein A is a phenylene radical, which can contain substituents from the series comprising alkyl(C 1 -C 6 ), alkoxy(C 1 -C 6 ), chlorine, bromine and nitro, or a naphthylene radical, by allowing at least 2 moles of phosgene to act on 1 mole of β-hydroxyethylsulfonyl-arylamine of the formula (2) n n HO--H.sub.2 C--H.sub.2 C--O.sub.2 S--A--NH.sub.2 (2) n n wherein A has the abovementioned meaning, in the presence of a catalyst at temperatures of about 100° to 200° C., if appropriate in an inert solvent. |
