Resumen

Chemical or electrochemical oxidation of the orthometallated amido dimeric complex [Pd-o-C6H4-C(Me)=N-NPh)L]2 (L= P(OMe)3,1) leads to double carbon-carbon coupling on the para carbons of the phenyl groups giving tetrapalladia units [Pd4]n+ (n = 0,1,2,3,4) related by fully reversible monoelectronic electron transfers. The species [Pd4]4+ undergoes splitting with CI- giving dimeric units [Pd2] where a 4,4′-biphenylene quinone diimine is trapped and stabilised between two palladia atoms; reduction of [Pd,] or [Pd4]4+ with CoCp2 affords [Pd4]0.
