Manganese photocatalysts enabled versatile room‐temperatureC−H arylation reactions by means of continuous visible‐light photoflow, thus allowing for efficient C−H arylations in 30 minutes with ample scope. The robustness of the manganese‐catalyzed photoflow strategy was shown by visiblelight‐induced gram‐scale synthesis, clearly outperforming the batch performance.
The present invention relates to compositions containing a zinc complex wherein a zinc atom carries two amide ligands, a lithium salt and a defined solvent. The compositions are stable and show high activity as reactants for metalation reactions, and thus provide a valuable tool in organic synthesis. Moreover, the invention relates to processes for the preparation of the compositions and to synthetic procedures using them.
