Photoinduced Electron Transfer-Mediated Substitutions in Aqueous Media

Abstract: This account intends to cover recent literature on photoinduced substitution reactions in water or aqueous media with synthetic utility.Interesting synthetic targets, such as benzothiazine rings, benzoxazoles, aromatic photosubstitutions on 6-fluoroquinoles, can be accomplished in a benign aqueous environment, reducing the impact of organic solvents, or the use of metals for substitution reactions.Synthetically-useful electron-transfer substitution reactions performed in aqueous media are noteworthy and not mu… Show more

“…From these data, the Gibbs energy change for electron transfer to 1 TCB* would be considerably more negative than to 1 DCN* (by ∼20 kcal/mol). This estimate is lower, by ∼9 kcal/mol, than that calculated from the singlet excited reduction potentials of 1 (69) The fitting of an experimental trace from our experiments into formation/decay kinetics was complicated by approximations used to take into account the small contributions from underlying fluorescence from unquenched 1…”

“…In the case of triphenylmethanol (TPML), electron transfer to 1 TCB* or 1 DCN* occurred, as evidenced by formation the The latter are best assigned to the radical cation of TPML formed within the laser pulse.…”
