The production of C 6 -C 17 oxygenated hydrocarbons from organotitanium compounds as described in this study represents a significant advancement in the field of organotitanium chemistry and artificial photosynthesis. Our work demonstrates that titanium-based catalysts, when properly tuned, can facilitate the formation of valuable, longer-chain oxygenated hydrocarbons under mild conditions. This method leverages the unique properties of titanium, particularly its ability to form stable intermediates while maintaining high reactivity, which has allowed for a cleaner and more direct pathway from simple starting materials, such as atmospheric CO 2 and water.
