electrochemical, kinetic, and synthetic study with a novel and easily accessible class of titanocene catalysts for catalysis in single‐electron steps. The tailoring of the electronic properties of our Cp2TiX‐catalysts that are prepared in situ from readily available Cp2TiX2 is achieved by varying the anionic ligand X. Of the complexes investigated, Cp2TiOMs proved to be either equal or substantially superior to
Cyclicvoltammetry‐based screening method for Cp2TiX‐catalyzed reactions is extended to the screening of solvents other than tetrahydrofuran for bulk electrolysis of the catalyst and radical arylation. It was found that CH3CN can be used as a solvent for both processes without additives. Furthermore, in tetrahydrofuran, squaramide L2 is more efficient than the previously reported supramolecular halide

Reductive cyclization of epoxides tethered to substituted anilines and aminopyridines in the presence of 3 mol % of titanocene dichloride and stoichiometric manganese metal promotes a radical annulation to form 3,3-disubstituted indolines and azaindolines.
