In the past decade, however, efforts to develop this reaction further have increased considerably, and many research groups have reported efficient coupling protocols, including enantioselective versions. These reactions most commonly employ palladium catalysts, but there are also some important reports ...

Pyridine−phosphine ligands 1−5 have been used to prepare neutral nickel dichloride complexes, neutral methylpalladium chloride complexes, and cationic methylpalladium complexes. The ligands consist of a diphenylphosphine and a pyridine moiety and differ in the backbone connecting those donor groups....
Recent remarkable progress in palladium and nickel-catalyzed reactions and its increasing impact on organic synthesis are surveyed. Aryl chlorides, which have been regarded as inactive compounds in nucleophilic substitutions, undergo facile Pd-catalyzed substitition. In these reactions of aryl chlorides, ...
