Palladium(II) tetrasulfophthalocyanine covalently immobilized on keratin protein grafted graphene oxide nanosheets as a new high-performance catalyst for C-C coupling reactions

Wool keratin protein, as an amphiphilic biomaterial, was extracted from natural wool and used to modify the surface of graphene oxide nanosheets. An aqua soluble palladium(ii) complex with a phthalocyanine ligand possessing the ability to covalently bind on keratin-protein-grafted graphene oxide nanosheets was used to chemically attach palladium(ii) complex to modified graphene oxide. The covalently supported palladium(ii) tetrasulfophthalocyanine complex revealed efficient catalytic reactivity by controlled temporary release of active species for Heck and Sonogashira coupling reactions in aqueous solution. Heck coupling of styrene and Sonogashira coupling of phenylacetylene with different aryl halides were successfully catalyzed by the synthesized palladium(ii) tetrasulfophthalocyanine covalently supported on keratin-protein-grafted graphene oxide nanosheets as a novel catalyst precursor. The controlled release of palladium active species prevents the formation of inactive palladium agglomerates under harsh conditions and consequently this controlled release leads to high catalytic performances.

Synthesis and characterization of tetra-substituted palladium phthalocyanine complexes

Tetra-substituted palladium phthalocyanine complexes with different electron withdrawing and electron donating substituents (-H, -NO2, -NH2, -Cl, -COOH, aryl thio) have been synthesized with a good yield. The synthesized complexes were characterized using XPS, UV-Vis, IR, Raman, XRD, TGA and electrochemistry. The XPS spectra show that the central metal ion is in the +2 state, while the UV-Vis spectra demonstrate split absorption peaks in the Q-band region 600-700 nm due to the presence of dimeric and oligomeric molecules in addition to the monomeric species. The UV-Vis and Raman spectra demonstrate a shift in the peaks/bands which is a result of the electron withdrawing and electron donating substituents at the periphery of the benzene ring compared to the parent palladium phthalocyanine. The thermogravimetic stability studies show that these complexes undergo two separate decomposition processes. The thermal stability for different complexes are in the order: PdPc a redox process and the redox behaviour observed is mainly due to the macrocyclic ring reduction process.

Spectroscopic and electrochemical studies on platinum and palladium phthalocyanines

The synthesis, spectroscopy and electrochemical characterisation of palladium and platinum phthalocyanines is reported. Electrochemical techniques were used in conjunction with electronic absorption spectroscopy to analyse the reduced and oxidised phthalo

Synthesis of phthalocyanine derivatives of the Ru, Rh, Pt and Pd metals under solvent free conditions using microwave irradiation

The phthalocyanine complexes of Ru, RhCl, Pt and Pd are easily prepared from phthalic anhydride and the corresponding metal salts by exposing to microwave radiation under solvent free conditions, which reduces reaction time considerably. The yield of metallophthalocyanines is increased by 12-15 % relative to that obtained by conventional methods.

PALLADIUM PHTHALOCYANINE AND ITS POLYMORPHIC FORMS

Pd(II) phthalocyanine (PdPc) was obtained by reaction of PdCl2 with phthalimide and urea in the presence of ammonium molybdate in boiling nitrobenzene, resulting in a good year equal to 68percent.This method has not been used previously.The following polymorphic forms were obtained: metastable α- and γ-PdPc, not previous described in the literature, and stable β-PdPc.The IR spectra and X-ray powder diffraction spectra of these phases were measured and interpreted.The results were compared with the literature data on polymorphic forms of other phthalocyanines.At this time we do not know if any of the PdPc polymorphs are isomorphous with the various forms of nickel, copper, and platinum phthalocyanine.
