OCTAHALOGENODIBENZO-<i>p</i>-DIOXINS

Abstract

Pentahalogenophenols have been converted to 1,2,3,4,6,7,8,9-octahalogenodibenzo-p-dioxins in almost quantitative yields using the halogens or halogen-producing compounds as initiators of the reaction. It is suggested that an intermediate in this reaction is the pentahalogenophenoxy radical.
