Light-Induced Activation of C–X Bond via Carbonate-Assisted Anion−π Interactions: Applications to C–P and C–B Bond Formation

We have presented a carbonate anion assisted photochemical protocol for the C–X bond activation. Anion−π interactions have been leveraged to generate aryl radicals from easily accessible aryl halides that are further utilized in C–P and C–B bond formation reactions with excellent reactivity and broad functional group tolerance. Spectroscopic investigations and DFT studies were conducted for mechanistic insights. This inexpensive method alleviates the use of a photocatalyst and the need of preactivation of the substrate for the light-induced activation of C–X bonds.
