General description

Benzeneseleninic acid oxidizes hydrazine or 1,2-disubstituted derivatives to corresponding diazenes.

Application

Benzeneseleninic acid was used as catalyst during the oxidation of sulfides to sulfoxides via ligand coupling on the iodine atom. It was also used in the preparation of 3-methoxy-17a-oxa-D-homoestra-l,3,5(10)-trien-17-one.
