4,4′-(((Perfluoropropane-2,2-diyl)bis(4,1-phenylene))bis(oxy))-bis(2,3,5,6-tetrafluoropyridine)
The title compound was synthesized in near-quantitative yield using nucleophilic aromatic substitution of 4,4′-(hexafluoroisopropylidene)diphenol (BPAF) with perfluoropyridine (PFP). The purity and structure were determined by NMR (1H, 13C, 19F), GC–EIMS,

Nickel-Catalyzed Reductive Cross-Coupling of Xanthate Esters With Aryl and Alkenyl Iodides. [PDF]
A nickel‐catalyzed reductive cross‐coupling of xanthate esters and aryl/alkenyl iodides is reported without the need for separate activators for the xanthate esters. The reaction utilizes a relatively low catalyst loading. Diarylmethanes with a good functional group variety can thus be synthesized indirectly from the corresponding benzylic alcohols ...

Flavin Catalysts in Organic Synthesis
Flavins and their congeners are potent catalysts for organic synthesis inspired by enzymatic transformations. In addition to catalysis in the flavin ground state via covalent intermediates, the excited singlet and triplet states unlock applications including photooxidation, photoreduction, and energy transfer via sensitization.
