Naturalo-benzopolysulfanes are often thought to exist as either the trisulfaneorpentasulfane; the nomenclature has evolved around such notions. No study makes reference to the possible existence of naturalo-benzoheptasulfanes. The work performed here indicates that a facile equilibration takes place between the tri-, penta-, and heptasulfanes (o-C6H4S3,o-C6H4S5, ando-C6H4S7) in solution. In these simpler (unnatural) compounds, the number of sulfur atoms can be established unequivocally from their independent syntheses. Theo-benzopolysulfanes, even after purification, yield mixtures of compounds in solution. A similar equilibration may be anticipated for the corresponding natural products.
