Sažetak

The nicotinium dichromate (NDC) oxidation of methyl phenyl sulfide (MeSPh) in acetonitrile, brought about by p-toluenesulfonic acid (TsOH), is first order in NDC and TsOH, and is zero order with respect to MeSPh in the concentration range investigated. The NDC oxidation of 14 para-, meta- and ortho-substituted phenyl methyl sulfides at 293-318 K complies with the isokinetic relationship but not to any of the linear free energy relationships; the isokinetic temperature lies within the experimental temperature range.
