Die vollständig C3‐selektive Arylierung von Thiophenen und Benzo[b]thiophenen wurde unter Verwendung von Pd/C als Heterogenkatalysator ohne Ligand und Additive unter milden Reaktionsbedingungen erreicht. Die Praktikabilität dieser Transformation beruht auf ihrer bemerkenswerten Toleranz für funktionelle Gruppen und der Unempfindlichkeit gegen H2O und Luft. Die Methode ist ebenso anwendbar auf Benzofuran,...
The completely C3‐selective arylation of thiophenes and benzo[b]thiophenes was achieved by using Pd/C as a heterogeneous catalyst without ligands or additives under mild reaction conditions. The practicability of this transformation is demonstrated by notable functional group tolerance and the insensitivity of the reaction to H2O and air. This method is also applicable to nitrogen‐ and oxygen‐containing...
