Si‐H‐Bindungsaktivierung: Parallelen der Lewis‐Säure‐Katalyse mit Brookharts Iridium(III)‐Pincerkomplex und B(C6F5)3

Anders und doch fast gleich: Die verblüffenden Gemeinsamkeiten von Brookharts Iridium(III)‐Pincerkomplex und dem elektronenarmen Tris(pentafluorphenyl)boran in Reaktionen über Si‐H‐Bindungsaktivierung werden vorgestellt. Die Koordinierung der Si‐H‐Bindung an eine der beiden Lewis‐Säuren steigert die Elektrophilie des Siliciumatoms und macht damit dessen Übertragung auf verschiedene Lewis‐Basen möglich (siehe Schema; Do=Aceton).

    Well shielded but highly active

    Biomacromolecules incorporated into tailored metal–organic frameworks using peptide modulators are well shielded but highly active thanks to carefully tuned nanoarchitecture. As scientists report in the journal Angewandte Chemie, this strategy can be used to synthesize an “artificial cell” ... more

    Sweet or Sour Natural Gas

    Natural gas that contains larger amounts of hydrogen sulfide (H2S) and carbon dioxide (CO2) is termed sour gas. Before it can enter a pipeline, it must be “sweetened” by removal of its acidic impurities. Through fine tuning of the ratios of two molecular components, it is possible to produc ... more

    Better Than Cyclodextrins

    Molecular containers that remove drugs, toxins, or malodorous substances from the environment are called sequestering agents. Scientists have developed a class of molecular containers that specifically sequester neurotransmitter antagonists. The barrel-shaped molecules called Pillar[n]MaxQ ... more
