A brave new world: the heteroatom chemistry of 1,3,2,4-benzodithiadiazines and related compounds

This review highlights the most important advances in the heteroatom chemistry of 1,3,2,4-benzodithiadiazines (pi-excessive and formally antiaromatic heterocycles), covering methods for synthesis, nontrivial features of the molecular and pi-electronic structure, spectral properties, and reactivity, in particular the transformations into persistent pi-radicals. The chemistry of 1,3,2,4-benzodithiadiazines is compared to that of related chalcogen-nitrogen compounds, both cyclic and acyclic. ((c) Wiley-VCH Verlag GmbH & Co.
