Heterogeneous Visible‐Light Photocatalysis in Continuous‐Flow: A Synergistic Strategy for Challenging Trifluoromethylation of α, α‐Diaryl Allylic Alcohols via 1,2‐aryl Migration

open access: yesAdvanced Science, EarlyView.
A continuous‐flow photocatalytic strategy is presented for the efficient synthesis of β‐trifluoromethyl ketones under visible light. Using a recyclable solid photocatalyst and an inexpensive CF3 source, the method enables rapid reactions, easy scale‐up, and smooth integration into multistep flow synthesis of bioactive molecules.

Atroposelective Construction of Axially Chiral Tetraarylethenes Via NHC‐Catalyzed Desymmetrization

open access: yesAdvanced Science, EarlyView.
We report the first NHC‐catalyzed atroposelective synthesis of axially chiral TAEs via oxidative desymmetrization of prochiral TAE dialdehydes. This catalytic strategy operates under mild conditions and accommodates a broad range of phenolic and nitrogen nucleophiles, delivering diverse axially chiral TAEs in good yields and up to 99% ee.

Photocatalytic Synthesis of Pentafluorosulfanyl Ketones, Acetals, and BCP Motifs Utilizing SF6

open access: yesAdvanced Science, EarlyView.
A photocatalytic single electron reduction strategy is reported for the activation and valorization of sulfur hexafluoride (SF6), a potent greenhouse gas. Under mild conditions, SF6 is reduced to generate pentafluorosulfanyl (SF5) radicals, enabling direct access to pentafluorosulfanyl ketones, acetals, and BCP motifs.
