Nitro is electron-withdrawing
Webb11 apr. 2024 · Carbon capture technology is an increasingly important part of our fight against climate change. This technology captures carbon dioxide (CO2) from the air, from power plants, industrial processes, and other sources and stores it away from the atmosphere. This helps reduce the amount of CO2 that is released into the air, and thus … Webb56π-Electron fullerene derivatives with electron-withdrawing cyano groups were synthesized by the reaction of 58π-electron fullerenes with NaCN, followed by in situ treatment with TsCN or MeOTf. The fullerene derivatives have low-lying LUMO levels, which are comparable with or lower than that of pristine C 60 .
