Peroxy esters phenols

Figure 13, indicates that the first mole of phenol is released in <30 s, the same elapsed time for the chemiluminescence to reach a maximum intensity. In fact, the measured rate constant r, for the rise in the chemiluminescence emission, is identical to the rate of the first phenol s release from the oxalate ester. Furthermore, the slower rate of release of the second phenol ligand has a rate constant that is identical to the chemiluminescence decay rate f. Thus, the model allows a quantitative analysis of the reaction mechanism, heretofore not available to us. We intend to continue this avenue of investigation in order to optimize the chemiluminescence efficiencies under HPLC conditions and to delineate further the mechanism for peroxy-oxalate chemiluminescence. 

Esters of phenols are obtained by treatment of aromatic hydrocarbons with peroxy acids [292], organic peroxides [1119, 1120], and lead tetraacetate or tetrakis(trifluoroacetate) [435, 449]. Benzene treated with tri-... 

Oxidations of aromatic aldehydes to formyl esters of phenols and to phenols are accomplished by hydrogen peroxide [171, 172, 173] or by organic peroxy adds such as peroxyacetic acid [259], peroxybenzoic acid [302], and m-chloroperoxybenzoic acid [5/5, 318] (equations 360-363). 

Base-catalysed oxygenation of the phenol (57) followed by Schotten-Baumann acylation yields the p-peroxy-quinol esters (58), which undergo a novel base-catalysed rearrangement with KOBu to give (59).
