Palladium(II) octaalkoxy- and octaphenoxyphthalocyanines: Synthesis and evaluation as catalysts in the Sonogashira reaction

Octaalkoxy- and octaphenoxysubstituted palladium phthalocyanines were used as a new family members of cross-coupling catalysts in the Sonogashira reaction. For the first time it was shown that terminal alkynes reacted mildly with p-substituted aryl bromides in gently conditions at room temperature under Pd and Cu-cocatalysis to give the corresponding phenylacetylenes. This protocol represents the use of palladium phthalocyanines as homogeneous catalysts in the Pd/Cu-promoted Sonogashira reaction.

Tetraaryltetraanthra[2,3]porphyrins: Synthesis, structure, and optical properties

A synthetic route to symmetrical tetraaryltetraanthra[2,3]porphyrins (Ar4TAPs) was developed. Ar4TAPs bearing various substituents in meso-phenyls and anthracene residues were prepared from the corresponding pyrrolic precursors. The synthesized porphyrins possess high solubility and exhibit remarkably strong absorption bands in the near-infrared region (790-950 nm). The scope of the method, selection of the peripheral substituents, choice of the metal, and their influence on the optical properties are discussed together with the first X-ray crystallographic data for anthraporphyrin.

Octabutoxyphthalocyanine, a New Electron Donor

The preparation of the 2,3,9,10,16,17,23,24-octabutoxyphthalocyanine zinc complex (1) is described.The electron-donating groups influence the properties of the compound.The oxidation-reduction potentials studied by cyclic voltammetry in solution shift by ca. 20 mV in the cathodic direction showing easier oxidation and harder reduction of the ligand of (1) compared to unsubstituted phthalocyanines.The interaction with iodine results in the formation of iodine complexes.The electrical conductivities are mentioned.
