Abstract

The photochemistry of 5-chloro-2-hydroxybenzonitrile 1 was studied in aqueous solution using transient absorption spectroscopy and product analysis. The triplet carbene 3-cyano-4- oxocyclohexa-2, 5-dienylidene 2 (λmax/nm 385, 368) was successfully detected and identified on the basis of its characteristic reactivity.
