  Platinum(IV) tetraphenylporphyrin dibromide complexes: synthesis, characterization, and electrochemistry

  摘要：

  Platinum(IV) porphyrins of the type [Pt-IV(p-X)(4)TPP]Br-2 where (p-X)(4)TPP is a para-substituted tetraphenylporphyrin have been synthesized by direct oxidation of their Pt(II) precursors with Br-2. Both the Pt(II) and Pt(IV) complexes have been characterized by visible and H-1 NMR spectroscopy and their electrochemical properties. In both the oxidation and reduction processes, a substituent effect is evident, and the reduction of Pt-IV-->Pt-II is identified. The oxidation and reduction potentials of the [ Pt-IV(p-X)(4)TPP] Br-2 complexes are compared to those of the [Pt-II(p-X)(4)TPP] precursors and [Pt-IV(p-X)(4)TPP]Cl-2 analogs. Addition of I-2 or I- to Pt(II) porphyrins does not result in oxidative-addition to form Pt(IV) porphyrins. Instead, the addition of I- to [Pt-IV(p-X)(4)TPP]Br-2 results in the reduction of the platinum to form the corresponding [Pt-II(p-X)(4)TPP)]. (C) 2000 Elsevier Science Ltd All rights reserved.

  Synthesis and properties of ms- and β-substituted Pt(II) and Pt(IV) tetraphenylporphyrinates

  摘要：

  The interaction of 5,10,15,20-tetraphenylporphyrin, 5,10,15,20-tetra-(4-chlorophenyl)porphyrin, 2-bromo-5,10,15,20-tetraphenylporphyrin, and 2,3,12,13-tetrabromo-5,10,15,20-tetraphenylporphyrin with platinum(II) chloride in boiling phenol has been studied. The corresponding platinum(II) porphyrinates have been synthesized; their subsequent treatment with bromine in chloroform resulted in platinum(IV) porphyrinates. The Pt(II) and Pt(IV)(Br)(2) porphyrinates have been identified by elemental analysis, electron absorption, IR, and H-1 NMR spectroscopy.
