A process for the production of cycloalkane epoxides from cycloalkenes in the presence of a boron-containing catalyst, oxygen and a carboxylate ion source via air oxidation is described. Alkali metal borates, alkali earth metal borates, rare earth borates and transition metal borates are useful catalysts. The boron catalyst may contain many different cations including lithium, sodium, strontium, barium, cerium, zirconium, vanadium, niobium, iron, cobalt, nickel, copper, zinc, and mixtures thereof. The reaction is conducted at a temperature in the range of 50 DEG to 150 DEG C. and a pressure of one atmosphere or greater. Cycloalkane epoxides are useful in the preparation of resins, plasticizers, etc.
