Greiner, Robert published the artcilePreparation of Polyfunctional Naphthyridines by Cobalt-Catalyzed Cross-Couplings of Halogenated Naphthyridines with Magnesium and Zinc Organometallics, Safety of 2,7-Naphthyridin-1(2H)-one, the main research area is polyfunctional naphthyridine preparation fluorescent; halogenated naphthyridine alkyl magnesium halidearylmagnesium halide cross coupling; zinc organometallic.
CoCl2 (5%) catalyzes cross-couplings of various halogenated naphthyridines with alkyl- and arylmagnesium halides. Also, arylzinc halides undergo smooth cross-couplings with various naphthyridines in the presence of CoCl2·2LiCl (5%) and sodium formate (50%), leading to polyfunctional arylated naphthyridines. Two of these arylated naphthyridines, e. g., I, are highly fluorescent, with quantum efficiencies reaching 95% and long excited-state lifetimes of up to 12 ns.
Organic Letters published new progress about Cross-coupling reaction. 67988-50-5 belongs to class naphthyridine, name is 2,7-Naphthyridin-1(2H)-one, and the molecular formula is C8H6N2O, Safety of 2,7-Naphthyridin-1(2H)-one.
