Title:
METHOD FOR PRODUCING 1,3-BENZOXATHIIN-4-ONE 1-OXIDE COMPOUND
Document Type and Number:
Japanese Patent JP2011011982
Kind Code:
A
Abstract:

To provide an industrially advantageous method for safely producing, in a good yield, a 1,3-benzoxathiin-4-one 1-oxide compound which is a raw material compound for a 1,2-benzoisothiazolin-3-one compound useful as an industrial antimicrobial agent and the like.

The method for producing the 1,3-benzoxathiin-4-one 1-oxide compound represented by formula (A) includes reacting the 1,3-benzoxathiin-4-one compound represented by formula (B) with an aqueous hydrogen peroxide solution in the presence of a catalyst or formic acid.
