Comparison of Oxidative Aromatic Coupling and the Scholl Reaction
TL;DR: The authors venture the hypothesis that, depending on the electronic structure of the substrates and the nature of the "catalyst", two different mechanisms can operate, one involves the intermediacy of a radical cation and the other the formation of a sigma complex between the acid and the substrate.

Nickel and palladium complex catalyzed cross-coupling reactions of organometallic reagents with organic halides
TL;DR: The discovery in 1972 by two research groups that dihalodiphosphinenickel(II) complexes exhibit extremely high catalytic activity for selective cross-coupling of Grignard reagents with sp2-carbon halides has aroused wide-spread interest in application in organic synthesis of this type and related reactions involving other organometallics than Grignards and not only nickel but also palladium complexes as catalysts as mentioned in this paper.
