摘要：

(Chemical Equation Presented) Unequal partners: One-electron reduction of a pincer-type palladium complex 1 results in collapse of the pincer system and formation of a novel bimetallic diamagnetic complex containing a linearly coordinated 14 e Pd0 center and a non-planar PdII unit (2). The reaction is reversed by oxidation with Ag+ or organic halides. The catalytic activity of 2 is investigated for the Heck reaction. © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
