Colloquia with Prof. Jeremy Rawson, University of Windsor

“Sulfur-Nitrogen Heterocycles: From Radicals to Magnetism, Coordination Chemistry and Catalysis”
J.M. Rawson, Dept of Chemistry & Biochemistry, University of Windsor.

In the last few decades sulfur-nitrogen radicals have developed from chemical
curiosities, with diverse and sometimes unpredictable chemistry, to building blocks
for molecular conductors, magnets, switches and photovoltaic devices. This talk
focuses on the development of organic magnets and switches based on 1,2,3,5-
dithiadiazolyl (1) and 1,3,2-dithiazolyl (2) radicals. In addition, recent developments
in benzo-1,2,4-thiadiazine chemistry are presented focussing on the coordination
chemistry of 3 and related metal-catalysed oxidation of benzothiadiazines to the
rare benzo-thiadiazine-S-oxides.
