Metal complexes based on functionalized 4-hydroxypolyfluorocoumarins
摘要:
4-Hydroxypolyfluorocoumarins containing an acetyl, 1-aminoethylidene, ethoxycarbonyl, or aminocarbonyl substituent on C-3 form coordination compounds with transition and rare earth metal cations. Some coumarin derivatives and their metal complexes show fluorescent properties.

Reactions of ethyl polyfluoro-4-hydroxy-2-oxo-2H-chromene-3-carboxylates with amines under mild conditions afforded alkylammonium polyfluoro-3-(ethoxycarbonyl)-2-oxo-2H-chromen-4-olates which efficiently inhibited hydrochloric acid corrosion of mild steel at low concentrations (10(-4)-10(-5) M).
