    摘要: This invention relates to 3-(phenyl/naphthyl)benz[d]isothiazole-1,1-dioxides wherein the phenyl or naphthyl substituent possesses an N-heterocyclic moiety in the para position. These compounds are useful as intermediates in the synthesis of certain 3,3-disubstituted-2,3-dihydrobenz[d]isothiazole-1,1-dioxide dyes which find utility as, for example, photographic optical filter agents and filter agent precursors.
