A number of other peroxygen based methods are known for alcohol oxidations. These include both organic peroxides, such as i-butyl hydroperoxide, and inorganic species such as perdisulfates. In all cases, the presence of metal species to catalyse the reaction is required. 

The Minisci reactions referred to above can also employ /-butyl hydroperoxide (TBHP), perdisulfate or dibenzoyl peroxide in the presence of hydrogen peroxide.493... 

Estimation of the enthalpy of formation of emeraldine can be approached from a different direction. The standard synthetic reaction using aniline and ammonium perdisulfate has been calorimetrically studied63 and shown to be exothermic by —439 5 kJmol-1. Reaction 13 is thus exothermic by —1756 20 kJmol-1 per emeraldine tetramer. 

In what concerns the solution containing bromide ions a marked sensitization of the rate of decomposition of perdisulfate was expected to occur as a result of the well known reactions... 

Aniline can be also used to modify a nanocomposite of PVK with Fe304 [220]. For modification, the nanocomposite is dispersed in an aqueous medium that contains potassium perdisulfate as oxidant under constant soiucation. To this dispersion aniline is injected. The system starts changing its color and eventually a black mass of a PANI PVK-Fc304 precipitates.
