- W133029973 abstract "Reactions of I0-methyl-9,10-dihydroacridine with various inorganic oxidants in 20% acetonitriie/80% water solvent mixture fall into two categories depending on the strength of the oxidant used. Rapid electron transfer to the strong oxidizing reagents, Ce'^ and IrCU^, produces dihydroacridine radical cations, AcrHz (Xmax 650 nm). This is followed by the rate-determining loss of a proton and rapid oxidation of thus formed AcrH* by the second equivalent of Ce'^ or IrCU^'. The protonation of AcrH* and deprotonation of AcrH2* exhibit significant kinetic isotope effects. The use of dzacridine in H2O/CH3CN yields the secondary and solvent isotope effects separately. A large normal secondary isotope effect of 1.86 ± 0.17 for the protonation' of the acridinium radical suggests a possibility of nuclear tunneling.
