Hexachlorocyclohexa-2,5-dien-1-one

Introduction

Hexachlorocyclohexa-2,5-dien-1-one is informally called hexachlorophenol (HCP). It is an efficient reagent for the chlorination of a wide variety of compounds and was used in several chiral organocatalytic reactions. HCP is a yellow to brown crystalline solid, which is usually prepared via electrophilic chlorination of phenol by chlorine gas in the presence of a metal chloride catalyst, such as iron(III) chloride.[1]
