摘要：

The photochemistry of several α-hydroxyarylacetic acids, including mandelic and benzilic acids, was studied in aqueous solution; these compounds photodecarboxylate, via α-hydroxyarylmethyl carbanions, with high quantum yields (≈ 0.2-0.7), to give the corresponding arylmethanols in high yield (> 50%), in contrast to the parent arylacetic acids, which typically have ≈ 0.01-0.03. © 1990.
