Photoinduced C-H monofluoroalkenylation with gem-difluoroalkenes through hydrogen atom transfer in batch and flow

Direct monofluoroalkenylation of C-H bonds are straightforward approaches for accessing multisubstituted monofluoroalkenes. However, general methods for the monofluoroalkenylation of C(sp3)-H bonds remain challenges. Here we report the development of a...

Hydrogen-atom and oxygen-atom transfer reactivities of iron(iv)-oxo complexes of quinoline-substituted pentadentate ligands

The reactivities of Fe(iv) oxido complexes of two pentadentate ligands are related to steric and electronic properties of the ligands.

SOMOphilic Alkynylation of Unreactive Alkenes Enabled by Iron-Catalyzed Hydrogen Atom Transfer

We report an efficient and practical iron-catalyzed hydrogen atom transfer protocol for assembling acetylenic motifs into functional alkenes. Diversities of internal alkynes could be obtained from readily available alkenes and acetylenic sulfones with excellent Markovnikov selectivity. An iron hydride hydrogen atom transfer catalytic cycle was described to clarify the mechanism of this reaction.
