Cover Feature: Post‐Formation of Fused Pentagonal Structure on Fjord Region of Polyaromatic Hydrocarbons under Hydrothermal Conditions (Chem. Eur. J. 38/2024)

Platinum catalyzes the cleavage of two C−H bonds at the fjord position of a polycyclic aromatic hydrocarbon (PAH), and the subsequent C−C bond formation gives a cyclopenta‐PAH. This post‐construction of the pentagonal structure is energetically challenging and requires high temperatures. With water...

Description
Summary:Platinum catalyzes the cleavage of two C−H bonds at the fjord position of a polycyclic aromatic hydrocarbon (PAH), and the subsequent C−C bond formation gives a cyclopenta‐PAH. This post‐construction of the pentagonal structure is energetically challenging and requires high temperatures. With water as the medium, it has been found that the monocyclization selectively occurs at a lower temperature. Fe2O3 is effective in suppressing side reactions. We found this reactivity in the Pt‐catalyzed deuteration of dibenzo[g,p]chrysene in D2O. More information can be found in the Research Article by H. Tsuji and co‐workers (DOI: 10.1002/chem.202400987).
