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

An efficient and rapid procedure for ring opening reaction of various epoxides with phenol and thiophenol derivatives was developed. The procedure can be obtained at room temperature under solvent-free condition in presence of (C4H12N2)(2)[Bicl(6)]Cl center dot H2O (1 mol %). This catalyst can be reused several times without significant loss of activity. (C) 2013 Elsevier Ltd. All rights reserved.
