METHOD FOR PREPARATION OF 2-METHYL-1,2-BENZISOTHIAZOLIN-3-ONE

A method for preparation of 2-methyl-1,2-benzisothiazolin-3-one from 1,2-benzisothiazolin-3-one by contacting 1,2-benzisothiazolin-3-one with an alkali metal hydroxide and dimethyl sulfate.

Process for preparing benzisothiazolinones

N-alkylated 1,2-benzisothiazolin-3-ones can be prepared in good yield and good selectivity by reaction of the lithium salt of 1,2-benzisothiazolin-3-one with an electrophilic alkylating agent.
