To a 4-t-butylcyclohexane-1,1-dihydroperoxide and terpinene (trapping reagent) in a stirred room temperature solution of carbon tetrachloride was added, over a period of five to ten minutes, a solution of bisacetoxyiodobenzene (BAIB) in carbon tetrachloride. Rapid bubbling commenced upon addition of the BAIB solution and ceased within a few minutes after addition was completed. Stirring was continued for 0.5 h, after which the solution was filtered through a plug of silica, which was washed with CH2Cl2. The residue obtained upon concentration was purified by column chromatography on silica gel to give 4-t-butyl cyclohexanone and the trapping product ascaridole (endoperoxide of terpinene).
