Photoinduced Ge(II)-Catalyzed Divergent Functionalization of Pyridyl Halides via Electron Donor-Acceptor Complexes.
We report a photoinduced Ge(II)-catalyzed strategy for divergent functionalization of pyridyl halides that leverages in situ electron donor-acceptor (EDA) complex formation to catalytically generate pyridyl radicals, enabling aryl, alkynyl, and alkenyl couplings under mild, protic conditions without an external photoca...
