Lead chloride superoxide

The carboxyperoxyl radical anion thus produced should be similar in reactivity to the hydroperoxyl radical, HO. The nucleophilic activity of the superoxide ion towards carbonyl groups in acid chlorides, esters and ketones is well documented The reaction between superoxide ion and the Py-Py" cation radical, which leads to destruction of the latter, would seem more likely to mitigate the long-term effects of the Py-Py rather than promote damage to components of the cell d . The occurence of Rh(bipy) -mediated photoreduction of alkenes with NADH models and... 

Oxidative cleavage of the indole 2,3-double bond has been achieved with ozone, sodium periodate, potassium superoxide, with oxygen in the presence of cuprous chloride, and with oxygen photochemically in ethanolic solution irradiation in an organic acid as solvent leads to oxidation at 2- and 3-alkyl groups. ...

After the first substitution, the remaining chloride of 31 is reactive enough for a second substitution, and this can lead to undesirable crosslinking of the proteins. Several examples of the use of 31 have been published, mainly in early studies, including the PEGylation of ovoalbumin [137,138], bovine serum albumin [20], superoxide dismutase [139], elastase [140], acyl-plasmin-streptokinase complex [141], trypsin [142], silk fibroin [143] and immunoglobulin [144], catalase [145,146], amongst others.
