Palladium-Catalyzed Difluorocarbene Transfer Enables Carbonylative Esterification of Aryl Thianthrenium Salts.
Aryl thianthrenium salt-mediated late-stage C-H carbonylation exhibits unique advantages in the site-selective modification of complex molecules. Herein, we disclose a palladium-catalyzed carbonylative esterification of aryl thianthrenium salts, in which commercially available potassium bromodifluoroacetate (BrCF2CO2K)...
