P-Toluenesulfonamide → N-tosyliminophenyliodinane

Participants

Reaction Steps

Diacetoxyiodobenzene (12.88 g, 40 mmol) was added to a solution of KOH (5.61 g, 100 mmol) and p-toluenesulfonamide (6.85 g, 40 mmol) in methanol (160 mL) at 8° C. A yellow color developed within 1 minute. The cooling bath was removed, and the solution was allowed to warm to RT with stirring for 3 hours. Water (180 mL) was added and the reaction was refrigerated overnight. The precipitate was collected by filtration and dried overnight in a vacuum dessicator to yield 10 g (66%) of a light yellow solid which was used with out further purification or characterization.
