Abstract: | reaction: see text] Efficient photodecarboxylation of (3-benzoylphenyl)alkanoic acids with formation of carbanions has enabled the determination of their protonation rate constants in water; the values obtained show that the reactivity toward protonation is determined by the size of the alkyl groups attached to the carbanion center. |
