Gold compounds have been used in oxidations of alkenes and alcohols1 while with silver compounds have almost not being explored.2 We report on a liquid-phase oxidative cleavage of 1,1-diphenylethylene to ketone by homogeneous unsupported water-soluble Ag/Au nanoparticles containing tannic acid and/or citrate as surface group (5 to 20 nm) in water at moderate temperatures and tert-Butyl hydroperoxide as an oxidant.  1.
