Description

General description

Cyclohexane undergoes oxidation in the presence of various oxidants such as hydrogen peroxide, tert-butyl hydroperoxide and molecular oxygen.

Application

Cyclohexane has been used to prepare a 1.3M solution of sec-butyllithium. It may be used as a starting reagent for the synthesis of adipic acid and ε-caprolactam.
