Photolysis of substituted alpha-chloro acetophenones has been studied
in different solvent systems wherein 1,2-aryl migration is found to be
media controlled. Effect of substituents on the migratory aptitude an
d a direct access to phenylacetic acids, in practical yields, has been
described. (C) 1997 Elsevier Science Ltd.
