Abstract
Abstract Arylsulfinic acids undergo smooth conjugate addition to p-quinones in air-and moisture-stable second generation room temperature ionic liquid [bmim] BF 4 under mild conditions to produce the corresponding arylsulfonylhydroquinones in excellent yields with high selectivity. In this reaction, ionic liquid plays the dual role as the solvent and the catalyst. The quinones show enhanced reactivity in ionic liquid thereby reducing the ...
