Claim:
1. A method for preparation of ketones, comprising steps of: providing an oxidant comprising at least one of a singlet state-oxygen atom O( reacting the oxidant and cycloalkanes at a pre-determined temperature and a pre-determined pressure without using transition metal catalysts or bromide catalysts and without using nitric acid or acetic acid as a solvent to produce cycloketones; wherein the pre-determined temperature is in a range between −10° C. and 50° C., and the pre-determined pressure is in a range between 0.8 atm and 1.2 atm; wherein the cycloalkanes comprise cyclopentane, cyclohexane, cycloheptane, cyclooctane or a combination thereof; the cycloketones comprise cyclopentanone, cyclohexanone, cycloheptanone, cyclooctanone or a combination thereof.
