Sultones, the internal esters of hydroxysulfonic acids, correspond to lactones, and are generally five- or six-membered rings, with or without olefinic bonds.Sultams, the nitrogen analogs of sultones, stem from gamma, delta, and epsilon-aminosulfonic acids. No sultones or sultams of beta-hydroxy or beta-ammo compounds, which would contain four-membered rings, are yet known.This article supplements the author's earlier review,1 but does not include lists of compounds or of physical properties.1 Some industrial applications are referred to, but not discussed. Synthetic methods for preparing sultones and sultams are illustrated and the chemical properties of these substances are reviewed.
