Sythesis of 2-(2-Alkoxycarbonylphenylthio)-1,2-benzisothiazolin-3-ones from 2-Sulfenamoylbenzoates

The Mechanism of formation of 2-(2-alkoxycarbonylphenylthio)-1,2-benzisothiazolin-3-ones, which were obtained by the heating of 2-sulfenamoylbenzoates, was investigated.It appears that transamination occurred on the sulfur atom of a 2-sulfenamoylbenzoate between the amino group and the 1,2-benzisothiazolin-3-one, which
