Peeking More Closely At Gold Catalysis

Chemists have learned more about two types of intermediates—cationic and carbene—that participate in gold catalysis
Department: Science & Technology

By employing a cyclopropene rearrangement reaction, chemists have uncovered more about the types of intermediates that participate in gold catalysis. Researchers often invoke electron-poor intermediates such as carbenes or cations to explain the mechanisms of gold catalysis, but such intermediates have tended to elude characterization. Günter Seidel, Richard Mynott, and Alois Fürstner of the Max Planck Institute for Coal Research, in Mülheim, Germany, report their efforts to generate gold carbenes by opening a . . .
