Abstract : A few natural products having asymmetric polysulphide moieties have been isolated, and improved methods of synthesis have enabled other asymmetric polysulphides to be secured. The availability of these compounds has enabled n.m.r. studies to be made, and these investigations have shown that the chemical shift of atomic nuclei adjacent to a sulphur group depends on its asymmetry. In addition, these compounds exhibit different circular dichroism. These advances have led to an increase in our knowledge of the stereochemistry of sulphur compounds and it therefore seems appropriate to present a review of the subject at this time. The review is divided into four sections dealing with sulphur, acyclic polysulphides, organic cyclic polysulphides, and inorganic cyclic polysulphides. (Author)
