ABSTRACT:
This invention relates to carbocyclic aryl compounds substituted with a tetrahydro-2H,4H-1,3,6-dioxazocino moiety and to the preparation thereof. 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.
