, p. 3854 - 3858 (2014)
An air-stable and easy-to-handle nickel precatalyst, (9-phenanthrenyl) Ni(II)(PPh3)2Cl, was examined for the cross-coupling reactions of aryl tosylates with arylboronic acids. Under the optimized reaction conditions, the catalytic system tolerates a wide range of activated, neutral and deactivated substrates. The selectivity of this cross-coupling reaction towards aryl tosylates and arylboronic acids has been investigated. It is proposed that ligand 1,1′-bis(diphenylphosphino)ferrocene (dppf) plays a key role in the coupling by enforcing a cis geometry in key intermediates and the active Ni(0) species.
1-(α-Aminobenzyl)-2-naphthol as phosphine-free ligand for Pd-catalyzed Suzuki and one-pot Wittig-Suzuki reaction

Air stable and easily accessible, 1-(α-aminobenzyl)-2-naphthols are used as efficient phosphine-free ligands in palladium-catalyzed Suzuki reaction for a variety of substrates under conventional heating as well as ultrasonic conditions. Multi-brominated aromatic substrates were successfully converted to corresponding arylated moieties with good conversion and selectivity. A novel one-pot two-step cascade reaction strategy involving Wittig and Suzuki reactions is developed for efficient synthesis of 4-styryl biphenyls (C 6-C2-C6-C6 unit). Copyright 2012 John Wiley & Sons, Ltd. Phosphine free 1-(α-aminobenzyl)-2- naphthol ligands are used for Pd catalyzed Suzuki and one-pot Wittig-Suzuki reaction to efficiently prepare styryl biphenyls (C6-C 2-C6-C6 unit). Copyright
