The syntheses of selenenate/seleninate esters and related derivatives by aromatic nucleophilic substitution (S(N)Ar) reactions of 2-bromo-3-nitrobenzylalcohol (13) and 2-bromo-3-nitrobenzaldehyde (17) with Na(2)Se(2)/nBuSeNa are described. The reaction of 13 with Na(2)Se(2) at room temperature afforded 7-nitro-1,2-benzisoselenole(3H) (15) instead of the desired
