Enantioselective 1,2-Arylfluorination of Alkenes using a Transient Directing Group Strategy – Paper Now in Press

The final version of our manuscript describing the palladium-catlayzed enantioselective 1,2-arylfluorination of alkenes using a transient directing group (TDG) strategy is online today in J. Am. Chem. Soc. In the study we apply Design of Experiments (DoE) to optimize this challenging three-component coupling of alkenes, arylboronic acids, and [F+] electrophiles, which helps to account for the complex interactions between variables in this system. We further elucidate the reaction mechanism using reaction progress kinetic analysis (RPKA). In terms of preparative applications, the method proceeds in high ee and d.r., allowing formation of full substituted C(sp3)–Ar and C(sp3)–F centers. The transformation is the first time that 1,2-difunctionalization has been achieved using a TDG approach and as such represents an important milestone for our lab and for the field. Hats off to Zhonglin, Luke, Mingyu, Zi-Qi, Van, and Yang!
