Synthesis and Characterisation of Unsymmetrical Porphyrazines Containing Bis(hydroxyethylthio) Substituents
摘要:
Unsymmetrical porphyrazines bearing a single peripheral bis(hydroxyethylthio) moiety were synthesised by mixed condensation of bis(2-hydroxyethylthio)maleonitrile and phthalonitrile. Complexation of the thioether groups of metal-free porphyrazine with PdCl2 further lowered the intensity of the Q-band absorption of the porphyrazine core. The new compounds were characterised by elemental analyses, IR, H-1 NMR, UV-Vis, and mass spectra.

The present invention relates to unsaturated vicinal dithioethers of general formula (I) wherein n is an integer from 1 to 12, wherein m is 0 or 1, wherein X is selected from formules wherein Y is selected from the group consisting of -CH2,-[-CH2,-O-CH2]3, -CH2- CH2-CH2-, -CH2- CH2-O-, -O-CH2-CH2-, -CH2-CH2-O-CH2-, and -CH2-O-CH2-CH2-; wherein, under the proviso that n is 1, m is 1 and R1 and R2 each are H; wherein, under the proviso that n > 1, R1 and R2 are selected from the group consisting of H, Na, CI, and Br, or R1 and R2 together form a bond making up a cycle. Furthermore the invention relates to mixtures of oligomeric unsaturated dithioethers according to the invention, to the use of the compounds and mixtures according to the invention in the separation of Pd (II) and to supports comprising the dithioethers according to the invention.

The crystal structures of several ligands and their palladiumcomplexes were determined as well as their electro- and photochemical properties, complex stability and behaviour in solution. Solventextraction experiments showed the superiority of some of our ligands over conventionally used extractants in terms of their very fast reaction rates.
