    Description / Table of Contents: Rearrangement Reactions of 2-Alkyl(Aryl)-3-arylimino-1,2-benzisothiazolines3-Chloro-1,2-benzisothiazolium chlorides 1 react with aromatic amines to give the 2-substituted 3-arylimino-1,2-benzisothiazolines 2 which can rearrange to the isomeric 1,2-benzisothiazolines 3 in an equilibrium reaction. On a formal basis this entails an exchange of positions of the substituents (R1 and R2) on the ring and exo nitrogen atoms. The nature of the substituents R1 and R2 is decisive for the position of equilibrium and the rapidity with which it is reached.
    Notes: 3-Chlor-1,2-benzisothiazolium-chloride 1 reagieren mit aromatischen Aminen zu den 2-substituierten 3-Arylimino-1,2-benzisothiazolinen 2, die sich in einer Gleichgewichtsreaktion in die isomeren 1,2-Benzisothiazoline 3 umlagern können. Dieses ergibt formal einen Platzwechsel der Substituenten (R1 u. R2) am Ring- bzw. exocyclischen Stickstoffatom. Die Lage dieses Gleichgewichtes und die Geschwindigkeit seiner Einstellung hängen entscheidend von der Art der Substituenten R1 und R2 ab.
