To investigate whether any active species of the catalyst were leaching
into the reaction medium, we carried out the reaction under selected
conditions with Ag/WOx-CNx catalyst. The reaction was stopped after 3 h,
the catalyst was separated by hot filtration and conversion of substrate
was estimated. The filtrate was added to the vessel again, and the reaction
was continued for another 10 h. No increase in substrate conversion was
observed; it remained the tungsten species of the catalyst into the reaction
mixture; the catalyst truly acted as if it were heterogeneous. This
observation confirms the complete absence of leaching of any active
species in reaction medium. Moreover, no trace of tungsten has been
found in ICP analysis of the hot filtrate portion.
