Synthetic applications of 3H‐1,2,4‐dithiazoles: Structure and reactivity studies

Synthetic applications of 3H‐1,2,4‐dithiazoles have been studied extensively. The facile synthesis of hitherto unknown 3H‐1,2,4‐dithiazole S‐oxides was realized by the mCPBA oxidation of 3H‐1,2,4‐dithiazoles. The structural information of the 1,2,4‐dichalcogenazole ring system was revealed by the ORTEP analysis of 3‐tert‐butyl‐5‐4‐chloro‐phenyl‐3H‐1,2,4‐dithiazole S‐oxide. The reactivities of 3H‐1,2,4‐dithiazoles are also discussed. © 2011 Wiley Periodicals, Inc. Heteroatom Chem 23:154–159, 2012; View this article online at wileyonlinelibrary.com . DOI 10.1002/hc.20764
