Unlike other N-alkylsulfonanilides, indolinesulfonamides hydrolyze in 98% sulfuric acid. Recent work in this laboratory has shown that rearrangement can be achieved by using polyphosphoricacid. A series of substituted indolinesulfonamides has been prepared and rearranged to their corresponding indoline arylsulfones.
