For many years since its discovery, Selenium has played the role of a bad boy who became a hero in organic transformations. Selenium dioxide, for instance, is one of the most remembered reagents in allylic oxida-tions, having been applied in the synt

The reactivity of the 2-arylselanyl pyridine derivatives L1–L4 towards dihalogens X2 (X = I, Br) and interhalogens IX (X = Cl, Br) was studied in CHCl3 or CH3CN. The solid products obtained were structurally characterized and their nature points ou
