Pr₂O₃ Supported Nano‐layered Ruthenium Catalyzed Acceptorless Dehydrogenative Synthesis of 2‐Substituted Quinolines and 1,8‐Naphthyridines from 2‐Aminoaryl Alcohols and Ketones

Abstract

Abstract Pr 2 O 3 supported Ru nanolayers and Ru nanoparticles catalysts were examined for the synthesis of quinolines. The Ru nanolayer was most active catalyst and showed a broad substrate scope. Structure‐activity relationship demonstrated that the metallic state and morphology of Ru as well as the basic site of Pr 2 O 3 were indispensable factors of this catalytic system.
