General description

Cyclohexane is a cyclic alkane that predominantly exists in chair conformation due to higher stability.

Application

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.
