α-Carbonylcarbenes (2a–c) generated by UV photolysis of 2-diazophenylacetic acid (1a), its methyl ester (1b) and 4-diazo-3-isochromanone (1c) in aqueous solution undergo conjugate addition of water across the entire carbonylcarbene moiety to give enols (3a–c) of the corresponding α-hydroxycarbonyl compounds. These carbenes are long-lived, with microsecond lifetimes in aqueous solution.
