Toxaphene is a complex mixture mainly consisting of polychlorinated bornanes, bornenes, bornadienes and camphenes. The systematic nomenclature of the individual compounds is long and, therefore, not very easy to use. There have been several proposals for simpler nomenclatures for these classes of compounds, but these all have serious limitations if structural information has to be deduced. The nomenclature proposed in this paper provides direct structural information. In addition, the presence of a pair of enantiomers can easily be read from the coded name.
