Polymer-supported IBX amide for mild and efficient oxidation reactions

A facile simple preparation of polymer-supported IBX amide (IBX amide resin) from chloromethyl polystyrene resin was demonstrated. The IBX amide resins were prepared with high loading levels (∼1.40 mmol g−1). These reagents were found to be mild and efficient oxidants through oxidation of a range of alcohols, sulfides and phosphites to the corresponding carbonyl, sulfoxide and phosphate compounds without over-oxidation at room temperature. Consumed IBX amide resins were reused up to five times without significant loss of oxidative activity after repetitive regeneration.
