Palladium‐Catalyzed Monofluoroalkylation of Aryl Iodides and Aryl Bromides with Nucleophilic Ethyl 2‐Fluoro‐2‐(trimethylsilyl)acetate

Abstract A palladium‐catalyzed monofluoroalkylation of aryl iodides and aryl bromides was developed using nucleophilic ethyl 2‐fluoro‐2‐(trimethylsilyl)acetate as a monofluoroalkyl source. The transformation proceeded with excellent substrate scope to afford a range of monofluoroalkylated products in good yields under mild conditions, and it proved feasible in a gram‐scale reaction. This protocol was successfully used in late‐stage modification of an estrone derivative, providing a facile route for research on the discovery of biologically active compounds and high‐performance materials. magnified image
