Photoinduced Iron-Catalyzed LMCT Enables Propargylic C(sp3)-H Activation to Access Polysubstituted α-Bromoenones

α-Bromoenones are highly valuable scaffolds with broad synthetic utility in organic synthesis. Conventional approaches to access these important motifs mostly rely on pre-functionalized substrates, stoichiometric electrophilic halogenating agents (e.g., X2,...
