摘要

Abstract A specific contraction of the phenolate form of 2-chlorophenol into a five-membered cycle has been observed in dilute aqueous solution (10− 3–10− 5 M) under irradiation. A cyclopentadienic acid is formed through a Wolff's rearrangement and hydrolysis. A spontaneous dimerisation of the acid occurs; the structure of the isolated dimer is established from 1 H (350 Mz) and 13 C NNR spectra.
