Condition Screening for Sustainable Catalysis in Single‐Electron Steps by Cyclic Voltammetry: Additives and Solvents

Abstract Cyclic voltammetry‐based screening method for Cp 2 TiX‐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 CH 3 CN 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 binder, Schreiner's thiourea L1 . The results extend the usefulness of the proposed time and resource‐efficient screening method for designing catalysis reactions in single‐electron steps.
