Abstract
This article describes developments concerning 1,3,2-dithiazole, 1,3,2-dioxazole and 1,3,2-oxathiazole containing molecules throughout 2006–19. Research effort has not been equally distributed among these molecular classes with a significant focus on 1,3,2-dithiazoles and their derivatives and less on the 1,3,2-dioxazoles and 1,3,2-oxathiazoles. New methods for the synthesis of 1,3,2-dithiazolium cations have been described, expanding the substrate scope of these molecules. New neutral 1,3,2-dithiazolyl radical analogs have been produced and extensively studied on reduction of 1,3,2-dithiazolium cations. Special attention has been given to the magnetic properties of 1,3,2-benzodithiazolyl radical derivatives primarily using X-ray diffraction to study the intermolecular molecular parameters of these molecules. Synthetic applications of 1,3,2-benzodithiazole S-oxides (particularly o-benzenedisulfonimide) as Brønsted-Lowry acid catalysts has also witnessed a significant acceleration over the last decade. © 2023 Elsevier B.V.
