Ionic Cyclopropenium-Derived Triplatinum Cluster Complex [(Ph3C3)(2)Pt-3(MeCN)(4)](2+)(BF4-)(2): Synthesis, Structure, and Perspectives for Use as a Catalyst for Hydrosilylation Reactions
This study presents a methodology for the synthesis of the ionic cyclopropenium-derived triplatinum cluster complex [(Ph3C3)(2)Pt-3(MeCN)(4)](2+)(BF4-)(2) and its analogue with the replacement of one of the BF4- anions with a Cl- anion, which represents a chain coordination polymer in crystalline fo...

| description | This study presents a methodology for the synthesis of the ionic cyclopropenium-derived triplatinum cluster complex [(Ph3C3)(2)Pt-3(MeCN)(4)](2+)(BF4-)(2) and its analogue with the replacement of one of the BF4- anions with a Cl- anion, which represents a chain coordination polymer in crystalline form. The structures of the complexes were studied by several physicochemical methods, primarily X-ray diffraction using synchrotron radiation and Pt-195 NMR spectroscopy in solution with measurement and analysis of the Pt-195-Pt-195 and C-13-Pt-195 spin-spin coupling constants. In addition, a high catalytic activity of the synthesized Pt-3 complex was observed in hydrosilylation reactions. The catalytic efficiency of the complex was found to be comparable to that of Karstedt's catalyst and in some cases even higher. |
