1,2-Oxa/Thia-3-Azoles

In this article, the chemistry of 1,2,3-dithiazoles and 1,2,3-oxathiazoles is covered from 2009 to 2018 inclusive. The 1,2,3-dithiazoles studied are: 1,2,3-dithiazolium cations, 1,2,3-dithiazolyl radicals, 1,2,3-dithiazole-5-ones and related thiones, imines and ylidene compounds, their 5,5-disubstituted derivatives, and their 2-oxides. 1,2,3-Oxathiazoles have been investigated in the form of their S-oxides and are also referred to as cyclic sulfamidites, sulfonimidates, sulfimidates and sulfamidates.
