Abstract We report on a convergent approach for the generation of dendrimers containing the [Ru 3 O(ac) 6 ] electroactive core, of great interest as multielectron transfer catalysts. The proposed strategy is based on the generation of the trimeric complex [{Ru 3 O(ac) 6 (4‐pic) 2 (pz)} 2 ‐μ 2 ‐Ru 3 O(ac) 6 (CH 3 OH)] 3+ (ac = acetate, 4‐pic = 4‐methylpyridine, pz = pyrazine). In this complex, the labile CH 3 OH ligand can be displaced by the bridging pyrazine ligand of [Ru 3 O(ac) 6 (pz) 3 ] 0 , leading to the self‐assembly of the [{[Ru 3 O(ac) 6 (4‐pic) 2 (pz)] 2 ‐μ 2 ‐Ru 3 O(ac) 6 (pz)} 3 ‐μ 3 ‐Ru 3 O(ac) 6 ] n + dendrimer containing 30 ruthenium atoms.(© Wiley‐VCH Verlag GmbH & Co.
