Tetrabenzporphyrin Complexes of Iron, Palladium and Platinum
نویسنده
چکیده
The syntheses and absorption spectra of Fe(II)TBP(pyridine)2, Pd(II)TBP, and Pt(II)TBP (TBP = Tetrabenzporphyrin) are reported. The emission spectra of PdTBP and PtTBP were measured. Both complexes exhibit only phosphorescence from the lowest triplet of TBP. The Fe complex was oxidized to the cation [FeTBP(pyn*dine)J+ which was characterized by its absorption and ESR spectrum. The emission spectra of Pd and PtTBP as well as the spectral properties of [FeTBP(pyridine)2]’ are discussed.

Background and Objectives: Transition metal complexes possess a variety of biological and pharmacological activities, such as antitumor, antimicrobial, anti-inflammatory, anti-diabetic, and free radical scavenging. Many studies have been carried out on platinum-based chemotherapy agents, however, most attention has been paid to non-platinum metal-based agents in order to find different metal comp...

A micellar solution of cetylpyridinium chloride (CPC) can separate into two phases due to a temperature change or to the addition of salts. Platinum(II), (IV) and palladium(II) reacted with chloride ions to form stable anionic complexes of PtCl4(2-), PtCl6(2-) and PdCl4(2-), respectively, and were adsorbed onto the CPC gel phase. The CPC phase plays the role of an ion-exchange adsorbent for the...

The synthesis of copper, gold, nickel, palladium, platinum, and iron complexes with open chain tetra-N-heterocyclic carbene (NHC) ligands via transmetalation using silver NHC complexes is presented. The obtained complexes show differing coordination geometries depending on both ligand structure and metal. While the complexes of the coinage metals form di- or tetranuclear structures, the group 1...
متن کاملSeparation and Recovery of Platinum and Palladium from Spent Petrochemical Catalysts Using Activated Carbon, Analysis of Two Kind of Most Used Catalysts in Petro Chemistry
The goal of this work is the separation and recovery of platinum and palladium from spent catalyst. The recovery consisted of separating the maximum amount of platinum and palladium from catalysts and changing them into usable forms. The petroleum and petrochemical units use Pt and Pd catalyst for reactions such as reforming and hydrogenation. Because these materials contain valuable metals...
