09 - 103Palladium-Catalyzed Aryl–Aryl Coupling in Water Using MolecularHydrogen: Kinetics and Process Optimization of a Solid-Liquid-GasSystem. — Halobenzenes (I) are coupled to the corresponding symmetricalbiaryls (II) using hydrogen and NaOH in the presence of catalytic amountsof Pd/C and polyethyleneglycol 400. The competitive direct reduction canbe minimized by optimization of the individual reaction conditions. —(MUKHOPADHYAY, SUDIP; ROTHENBERG, GADI; WIENER, HAROLD;SASSON, YOEL; Tetrahedron 55 (1999) 51, 14763-14768; Casali Inst.
