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

Experimental data supporting the claim that CO 2 could be used as an oxidant for light-assisted oxidation of aldehydes to carboxylic acids recently published by S. L. Jain et al. , Chem. Commun. , 2022, 58 , 2208 could be mistrusted.
