Generation of a Ground‐State Electron Donor Utilizing Stored Light Energy
Chemistry – A European Journal, EarlyView.Chemically stored light energy enables the generation of dianion reductants (∼−2.7 V) from vicinal diols derived from diaryl ketone photodimerization. These ground‐state electron donors efficiently reduce challenging substrates at room temperature, including aryl bromides, alkyl iodides, and sulfonamides.
