Oxidation of benzene by radiolytically produced OH radicals

Oxidation of cinnamic acid derivatives: A pulse radiolysis and theoretical study

“…The Å OH radical, being an electrophile, adds preferentially at the electron rich sites ortho and para to the substituent [2][3][4][5][6][7][8] and thus, these studies have provided valuable mechanistic information on structure-reactivity relationship.…”

Decomposition of halophenols in room-temperature ionic liquids by ionizing radiation

“…The G(P) and G(Cl -) values in P13-TFSI, P14-TFSI, and PP13-TFSI were less than 30% of the G(-CP) value, and thus the decomposition of CP is considered to primarily occur via other reactions such as dimerization (path 2). These radicals are also known to undergo internal isomerization to form phenoxyl radicals, which then can undergo dimerization to form various substituted biphenyls (Klein and Schuler, 1978;Land and Hanrahan, 2005;Taguchi et al, 2006;Ye and Schuler, 1989). Using Reichardt's dye, the polarity values, E T (30), of P13-TFSI, P14-TFSI, and PP13-TFSI were found to be 50, 51, and 50 kJ mol À 1 , respectively, and were lower than that of DEMMA-TFSI (Table 1).…”

Electrochemical discolouration and degradation of reactive dichlorotriazine dyes: reaction pathways

“…so that the yield of • OH per 100 eV absorbed radiation, G(OH), is equal to 6.0 [39]. Since G(H) = 0.56, in irradiated N 2 O-saturated aqueous solutions, the • OH radicals constitutes more than 90% of all the radicals produced.…”

“…The dimer generated via recombination of two cyclohexadienyl radicals may not have the conjugated colour giving part when it consists of two cyclohexadiene rings. The radical disproportionation leads to compounds that contain cyclohexadiene ring and another compound with extensive conjugation in the molecule characteristic to the dye and with an additional OH group [36,39].…”
