The synthesis of diarylethyne-linked multiporphyrin arrays requires Pd-mediated coupling conditions that are performed in dilute solution in the absence of copper and that give reaction mixtures that are easily purified. We previously developed coppe

A complex containing four manganese centres is thought to be the catalytic site of photosynthetic water oxidation. The structure and mechanism of action of this complex are largely unknown. Mn-coordination complexes can be used as models for the mang

The dimer [( 1 )Mn III ] 2 (μ-O) ( 3 ) was synthesized by oxygenation of the mononuclear Mn(II) complex in CH 3 CN. The ligand used was 3,3′-17-crown-6-SAL-3-CH 3 -OPHEN ( 1 ). Dimer 3 reacted with KPF 6 and Ba(SO 3 CF 3 ) 2 in DMF forming 3 ·2KP
