Fluorous IBX

Several modified catalysts for the iodine(V)-mediated oxidation of alcohols have been developed based on IBX derivatives and analogues (Figure 4.2). In particular, the fluorous IBX 91 works efficiently as a catalyst for the oxidation of various alcohols to the corresponding carbonyl compounds in good to high yields... 

Fluorous IBX 91 can be regenerated from fluorous IBA, which is readily recovered from the reaction mixture by simple filtration. The recovered reagent 91, without further purification, retains its catalytic activity...
