摘要:
The metal-assisted isomerization of the pyrrolenine anion 1,1,2-tricyano-2-(3,4-dicyano-5-imino-2,5-dihydro-1H-pyrrol-2-ylidene)ethanide (C11N7H2-, L') to the 1,2,6,7-tetracyano-3,5-diimino-2,5-dihydro-pyrrolizinide anion (L) has been studied in solutions of CH2Cl2 or tetrahydrofuran (THF) with the palladium(II) chlorides, PdCl42- or Pd2Cl62-, respectively. In THF the bis-chelate PdL(2) and the mono-chelate PdLCl(2)(-) are formed. In CH2Cl2, only mono-chelate species are formed such as PdLCl(2)(-) or PdLCl(CN)(-). The mono-chelate species show an optical spectrum, due to the drop PdL chromophore, qualitatively more similar to that of the corresponding phthalocyanine, PdPc, than that of PdL(2).
