Heterogeneous Palladium-Catalyzed Synthesis of Aromatic Ethers by Solvent-Free Dehydrogenative Aromatization: Mechanism, Scope, and Limitations Under Aerobic and Non-Aerobic Conditions
derivatives and alcohols, both non-aromatic precursors, aryl ethers could be synthesized in good yields and with good selectivities in the presence of a catalytic amount of Pd/C, in one step, without added solvent, in a reaction vessel open to air. For less reactive substrates, the addition of 1-octene in a closed system undernon-aerobicconditions improved the conversion. In addition, the catalyst could
