The synthesis of novel N,N′-substituted para-phenylenediamines bearing side-chains containing one or two monoselenide linkages is described. Reductive alkylation of para-phenylenediamines with oxoselenides using sodium cyanoborohydride in methanol gives good to high yields of these compounds. Compounds containing one selenide linkage react with 3 mol equivalents of ozone, and those containing two selenide
