| titleOfInvention | Synthetic procedure for the preparation of 1,2-Bencisothiazolin-3-one |
| abstract | A process for producing a 1,2-benzothiazolin-3-one compound of the general formula (I) ** Formula ** wherein R1 is selected from the group consisting of hydrogen, C1-C4 alkyl, OR2, C ( O) OR2, Cl, Br, I and NO2, wherein R2 is hydrogen or C1-C4 alkyl comprising steps a) reacting a 2-halobenzonitrile compound of the general formula (II) ** Formula ** in wherein X is Cl or Br with a thiol compound of the general formula (III) R3-SH (III), wherein R3 is selected from the group consisting of unsubstituted or at least monosubstituted C5-C22 alkyl, aryl C5-C14 unsubstituted or at least monosubstituted and aralkyl C7-C18 unsubstituted or at least monosubstituted, in which the substituents are selected from the group consisting of F, Cl, Br, I, OH, NH2, C1- alkyl C8 and OR4, wherein R4 is hydrogen or C1-C4 + alkyl in the presence of at least one base (B) to form an intermediate of the general formula (IV) ** Formula ** b) react the i The intermediate of the general formula (IV) obtained in step a) with a halogenating agent in the presence of water to form a reaction mixture (RM), comprising the 1,2-benzothiazolin-3-one of the general formula ( I) and a halide compound of the general formula (V) in which X1 is Cl or Br. |
