“…It leaves only α‐hydrogen abstraction as a means of formate production, accounting for the minor amounts of this side product after cell operation, and virtually zero using KO 2 reactions as a probe (Figure b, inset). Although the literature suggests that both sites are equally as susceptible to hydrogen abstraction, based on the greatly decreased lithium formate production, our results clearly demonstrate that β‐hydrogen abstraction is the dominant pathway. This is consistent with thermodynamic principles, in that formation of an oxygen‐stabilized 2° radical (Figure , Path 2) should be more favorable than formation of an oxygen‐stabilized 1° radical (Figure , Path 3).…”

“…The main products of decomposition of DME by strong oxidizing agents in aqueous solution are methanol, formaldehyde, and formic acid . We believe that under aprotic conditions, the analogous oxidation byproducts are formed via hydrogen abstraction‐initiated mechanisms, as illustrated in Figure .…”

“…40 The radical thus formed (3) may undergo b-scission (C-O scission) to give other radicals (5, 4 0 ) and unsaturated fragments (6, 7). 41 Actually, unsaturated compounds (6; m ¼ 1, and 7; m ¼ 0) were detected. The resultant radicals (4 0 , 5 0 ) may undergo recombination by radical coupling to generate various glymes (1 0 ) comprising from monoglyme (n ¼ 1), diglyme (n ¼ 2), triglyme (n ¼ 3), and other oligomers, which were detected up to n ¼ 6 aer 5 cycles.…”

“…For example, ronidazole forms chlorinated products through thermal reactions with HOCl, hydroxylated products during direct photolysis, and a combination of products during chlorine photolysis. 110 Therefore, contaminant transformation may result in a wide range of products (Table 4), including the formation of chlorinated products 48,54,103,107,110,112,115 and mineralization to CO 2 in some cases. 48,92,103,105,107,110,112,115 Although degradation of many compounds is generally very efficient, 42 some compounds are relatively less susceptible to oxidation in the AOP (e.g., carbamazepine, 42 cyclohexanoic acid, 40 desethylatrazine, 42 and TCE 56 ).…”

“…51 Additionally, contaminant transformation product distributions can be dependent on initial chlorine concentrations, with a shift from organic products to mineralization observed at very high chlorine concentrations. 48,103,107,110,112 Finally, contaminant transformation rates are also dependent on light intensity, 107,109 but the effect of irradiation wavelength on organic compound removal has not been systematically investigated.…”
