Although halogenated hydrocarbons (HHCs) such as halomethanes and haloethylenes are widely used as solvents and raw materials, their high toxicity and chemical stability have led to problems such as remaining in soil and marine environments. In this study, we attempted to develop a new synthetic method (chemical upcycling) that can directly convert these HHCs into useful chemical products. We have developed an approach to generate phosgene from chloroform in situ using the C-H oxygenation reaction by photoactivation of chlorine dioxide. This paper introduces the details of these reactions and the future potential of the chlorine dioxide photo-modification.
