A highly efficient and practical oxidative dearomatization of phenols using sodium hypochlorite pentahydrate as an inexpensive, strong oxidant is reported for the first time. The oxidation reactions proceeded very rapidly in the presence of water to give the desired products in excellent yields, and sodium chloride and water were the only by-products derived from the oxidant.
3-Substituted benz[d]isothiazole-1,1-dioxides

, (2008/06/13)
This invention relates to 3-(phenyl/naphthyl)-benz[d]isothiazole-1,1-dioxides wherein the 3-phenyl or the 3-naphthyl group is substituted in the para position with hydroxy blocked with certain protecting groups. 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, for example, as photographic optical filter agents and filter agent precursors.
