a salt which upon careful neutralization affords a fused bis-gamma-pyrone. The bis-gamma-pyrone forms stable metal complexes with Li, Mg, Cu(II), Ni(II), Zn, Fe(II), Co(II) and Ba perchlorates whose crystal structures reveal that the ligand possesses significant bispyrylium character while the metal is coordinated at the negatively charged edge of the structure.
脱氢乙酸在高氯酸存在下与乙酸酐反应,生成一种盐,将其仔细中和后可得到稠合的双-γ-吡喃酮。双γ-吡喃酮与Li,Mg,Cu(II),Ni(II),Zn,Fe(II),Co(II)和Ba高氯酸盐形成稳定的金属络合物,其晶体结构表明该配体具有显着的双pyryrylium特性而金属则在结构的带负电荷的边缘配位。
