General description

Cyclohexane is a cyclic alkane that predominantly exists in chair conformation due to higher stability.[6] It participates as starting reagent in the photonitrosylation process (PNC process) and affords ε-caprolactum.[1] Its oxidation by employing various oxidants such as hydrogen peroxide, tert-butyl hydroperoxide and molecular oxygen has been reported.


Cyclohexane has been used in the following studies:

  • As a solvent in the synthesis of europium dibenzoylmethide triethylammonium (EuD4TEA).
  • Preparation of poly(dimethylsiloxane) (PDMS) microchip.
  • As a solvent in the two-solvent (cyclohexane/water) deposition method for the preparation of monometallic 5wt% Ni containing catalysts.

Cyclohexane may undergo oxidation using hydrogen peroxide as oxidant and in the presence of a polyoxotungstate catalyst to form cyclohexanone and cyclohexanol as the main products. Its dehydrogenation in the presence of Ni-Cu/SiO2 catalysts forms benzene in good yield.
