Polyanilinc (PANI)-Pt and polypyrrolc (PPy)-Rh compositcs obtained by chcmical reduction of Pt4' or Rh3* ions preformed in the prescncc of the polymers have been used as catalysts of eyclohexcnc oxidation by molecular oxygen under mild conditions. It has been found that PPy-Rh is more active than PANI-Pt in the first stage of the reaction resulting in 2-cyclohcxcnc-1-hydroperoxide. Differences in selectivity of the second stage of cyclohcxcnc oxidation yielding cyclohcxene epoxide, 2-cyclohexcnone and 2-cyclohexcnol over both catalysts have been also observed.
