5 Other Metallic Oxidants - Copper Sulfate or Oxone-Alumina 

Under these solvent-free conditions, the oxidation of primary alcohols (e. g. benzyl alcohol) and secondary alcohols (e.g. 1-phenyl-l-propanol) is rather sluggish and poor and is of little practical utility. Consequently, the process is applicable only to a-hydroxyketones as exemplified by various examples including a mixed benzylic/ali-phatic a-hydroxyketone, 2-hydroxypropiophenone that delivers the corresponding vicinal diketone [106,107]. 

6 Nonmetallic Oxidants lodobenzene Diacetate (IBD)-lmpregnated Alumina 

Several organohypervalent iodine reagents have been used for the oxidation of alcohols and phenols such as iodoxybenzene, o-iodoxybenzoic acid (IBX), bis(trifluoroa-cetoxy)iodobenzene (BTI), and Dess-Martin periodinane etc. But the use of inexpensive iodobenzene diacetate (IBD) as an oxidant, however, has not been fully exploited. Most of these reactions are conducted in high boiling DMSO or toxic acetonitrile media that results in increased burden on the environment.
