A Short, Versatile Route Towards Benzothiadiazinyl Radicals

Clark, Ewan R, Saines, Paul J. (2021) A Short, Versatile Route Towards Benzothiadiazinyl Radicals. Chemical Science, . ISSN 2041-6520. (doi:10.1039/D1SC04248C) (KAR id:91710)


A family of substituted 1,2,4-benzothiadiazine 1-chlorides have been prepared by treatment of N-arylamidines in neat

thionyl chloride at reflux. The S(IV) 1-chlorides are readily reduced under mild conditions to persistent 1,2,4-

benzothiadiazinyl radicals which have been characterised by EPR spectroscopy and cyclic voltammetry. Crystallographic

studies on isolated radicals indicate that the radicals dimerise via pancake bonding in the solid-state, resulting in

spin-pairing and net diamagnetism.
