Abstract
AbstractThrough an optimized synthetic procedure, metalloligand 5, which features a hetero‐Pacman scaffold comprising a porphyrin and a terpyridine moiety, has been assembled by a double Suzuki reaction. In a subsequent step, a ruthenium‐bipyridine fragment was introduced at the terpyridine coordination site of metalloligand 5 to form complex 6, which was fully characterized and its potential application in water oxidation catalysis tested. A number of side‐products were isolated and characterized during the two‐step synthesis procedure, including a hydroxylated version of the boronic acid substituted precursor molecule derived by a base‐assisted rearrangement. The compounds described herein extend the Pacman concept to the assembly of different metal combinations with different coordination spheres and their interactions in the activation of small molecules.
