Abstract

(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 Pd^II unit (2). The reaction is reversed by oxidation with Ag⁺ or organic halides. The catalytic activity of 2 is investigated for the Heck reaction.
