Reply to the ‘Comment on “CO2 as oxidant: an unusual light-assisted catalyst free oxidation of aldehydes to acids under mild conditions”’ by S. R. Khan, S. Saini, K. Naresh, A. Kumari, V. Aniya, P. K. Khatri, A. Ray and S. L. Jain, Chem. Commun., 2022, 58, 2208

Our recent Communication (S. R. Khan et al., Chem. Commun., 2022, 58, 2208) suggested that CO2 can be used as a potential oxidant under light irradiation without using any catalyst for the oxidation of aldehydes to acids at room temperature. The Comment based on the published literature on the catalytic oxidation of aromatic aldehydes by CO2 and thermodynamical data argued on the realism of the experimental data.
