Photophysical properties of three coordinated copper(i) complexes bearing 1,10-phenanthroline and a monodentate phosphine ligand.

Daichi Kakizoe et al.

Dalton transactions (Cambridge, England : 2003), 46(43), 14804-14811 (2017-10-19)

We report the synthesis and photophysical properties of Cu(i) complexes with 1,10-phenanthroline (phen) and monodentate phosphine ligands. Single crystal X-ray structural analysis revealed that these have three-coordinated trigonal planar geometries. We also found that one of them, [Cu(phen)(Johnphos)]BF

Biaryl phosphane ligands in palladium-catalyzed amination.

David S Surry et al.

Angewandte Chemie (International ed. in English), 47(34), 6338-6361 (2008-07-30)

Palladium-catalyzed amination reactions of aryl halides have undergone rapid development in the last 12 years, largely driven by the implementation of new classes of ligands. Biaryl phosphanes have proven to provide especially active catalysts in this context. This Review discusses

Palladium-catalyzed Suzuki-Miyaura cross-coupling reactions employing dialkylbiaryl phosphine ligands.

Ruben Martin et al.

Accounts of chemical research, 41(11), 1461-1473 (2008-07-16)

The cores of many types of polymers, ligands, natural products, and pharmaceuticals contain biaryl or substituted aromatic structures, and efficient methods of synthesizing these structures are crucial to the work of a broad spectrum of organic chemists. Recently, Pd-catalyzed carbon-carbon
