Generation of a Ground-State Electron Donor Utilizing Stored Light Energy. [PDF]
ChemistryChemically 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.

ANTIOXIDANT ACTIVITY OF XANTHONE DERIVATIVES. [PDF]
Acta poloniae pharmaceutica, 2016 Certain xanthone derivatives, such as these present in mangosteen fruits, show strong antioxidant activity. On the other hand, evidences accumulated that oxidative stress is involved in epileptogenesis. Therefore, the aim of the present study was to estimate total antioxidant capacity (expressed as a ferric reducing antioxidant power - FRAP) and ...
