title: Dinuclear palladium complexes--precursors or catalysts?
abstract: Calculations help: Recent work from Schoenebeck's group has demonstrated beyond reasonable doubt that the dimeric LPd(I) Br catalysts that are widely used in coupling chemistry operate through prior formal reduction to an LPd(0) species. Conversely, L(2)Pd(0) catalysts can be activated by oxidation. In other cases a binuclear species can persist through the catalytic cycle.
