Oxidation of alcohols with IBX

For the oxidation of alcohols with IBX, kinetic evidences are consistent with the following mechanism.91... [Pg.204]

Several research groups have used ionic liquids for the oxidation of alcohols with o-iodoxybenzoic acid (IBX) or Dess-Martin periodinane (DMP). Alcohols undergo smooth oxidation with IBX or with DMP in hydrophilic [bmim]BF4 (structure 36, Figure 6.2) and hydrophobic [bmimjPFe (structure 37) ionic liquids at room temperature under mild conditions to afford the corresponding carbonyl compounds in excellent yields with high selectivity [54]. Similar results were obtained for the oxidation of alcohols with IBX and DMP using ionic liquid [bmim]Cl (l-butyl-3-methyUmidazoliumchloride) [55,56]. IBX- and DMP-promoted oxidations are faster in ionic liquids compared to conventional solvents such as DMSO, DMF, ethyl acetate and water. Recovery of the by-product iodosobenzoic acid is especially simple in ionic liquids. The recovered ionic liquids can be recycled in subsequent reactions with consistent activity. [Pg.419]
