Method for producing 1,2-benzisothiazol-3-ones |
摘要 |
A method for producing a 1,2-benzisothiazol-3-one, having the steps of carrying out a reaction of a 2-(alkylthio)benzaldehyde with a hydroxylamine to give a 2-(alkylthio)benzaldehyde oxime and carrying out a reaction of the 2-(alkylthio)benzaldehyde oxime with a halogenating agent; and a method for producing a 1,2-benzisothiazol-3-one, having the steps of carrying out a reaction of a 2-halobenzonitrile with an alkanethiol in a heterogeneous solvent system in the presence of a base to give a 2-(alkylthio)benzonitrile and carrying out a reaction of the 2-(alkylthio)benzonitrile with an halogenating agent in the presence of water.
