Organoselenide and organotelluride compounds are of great interest in “green” chemistry because of their ability to activate hydrogen peroxide. Hydrogen peroxide by itself can be a slow oxidizing agent, but when activated it is kinetically useful. Organoselenide and telluride dendrimers prepared by Detty and colleagues have shown significant catalytic activation of H2O2, but were not water soluble and were prone to selenoxide syn-elimination. 4-4'-Dihydroxydiphenyltelluride, although not water-soluble, has been shown to catalytically activate H2O2 while avoiding telluroxide elimination. Incorporation of the 4-4'- dihydroxydiphenyltelluride moiety into the architecture of a dendrimer has been troublesome. As a substitute, 4-hydroxy-4'-methoxydiphenyltelluride has been synthesized and attached to small dendrimers with some success. The extent of H2O2 activation by these organotelluride catalysts is to be determined.
