Abstract
The metal-assisted isomerization of the pyrrolenine anion o-5-imino-2, 5-dihydro-1H-pyrrol-2-ylidene)ethanide (C11N7H2-, L') to the 7-tetracy ano-3,5-diimino-2,5-dihydro-pyrrolizinide anion (L) has been studied i n solutions of CH2Cl2 or tetrahydrofuran (THF) with the palladium(II) chlorides, PdCl42- or Pd2Cl62-, respectively. In THF the bis-chelate P dL(2) and the mono-chelate PdLCl(2)(-) are formed. In CH2Cl2, only mon o-chelate species are formed such as PdLCl(2)(-) or PdLCl(CN)(-). The mono-chelate species show an optical spectrum, due to the drop PdL chr omophore, qualitatively more similar to that of the corresponding phth alocyanine, PdPc, than that of PdL(2).
