We have developed a photoinduced transition-metal-free decarbonylative strategy at ambient temperature through non-covalent interactions to achieve vinyl sulfones. Traditionally, decarbonylative functionalization is accomplished using transition metal catalysts at elevated temperatures. The π–π interaction facilitates the elimination of CO to generate vinyl radical, thereby promoting the creation of C–S bonds with the sulfonyl radical. These interactions and the overall process were illuminated by spectroscopic investigations and mechanistic studies.

通过 EDA 络合实现光诱导单电子转移，实现脱羰基 C（sp2）–S 键的形成


我们开发了一种在环境温度下通过非共价相互作用的光诱导无过渡金属脱羰策略，以获得乙烯基砜。传统上，脱羰基官能团化是在高温下使用过渡金属催化剂完成的。π-π 相互作用有助于消除 CO 以生成乙烯基自由基，从而促进与磺酰基自由基形成 C-S 键。这些相互作用和整个过程通过光谱研究和机理研究来阐明。
