Visible-Light-Induced\nSynthesis of Azlactone Monomers\nand Dimers utilizing SF<sub>6</sub> as both Condensation Agent and\nOxidant

The visible-light-mediated continuous dehydration condensation\nand oxidative radical dimerization, featuring sulfur hexafluoride\n(SF<sub>6</sub>) as both a condensation agent and oxidant, have been\ndeveloped. This photocatalytic method uses commercially available\nN-protected amino acids as substrates and enables the formation of\nazlactone monomers and dimers, facilitating efficient utilization\nand degradation of greenhouse gas SF<sub>6</sub>.
