A highly stable, Au/Ru heterobimetallic photoredox catalyst with a [2.2]paracyclophane backbone The unique "bent and battered" structure of [2.2]para cyclophane features planar chirality, high rigidity and enables transannular electronic communication which makes this scaff old an ideal playground for the investigation of cooperative eff ects in distance-defi ned heterobimetallic complexes. In the featured heterobimetallic Au/Ru complex, [2.2]paracyclophane acts as a backbone, holding the two

The Au/Ru complex is easily accessible, exhibits high stability and shows promising properties as photoredox catalyst in a visible-light mediated arylative Meyer-Schuster rearrange ment. We report the synthesis and catalytic application of a highly stable distance-defined Au/Ru heterobimetallic complex. [2.2]Paracyclophane serves as a backbone, holding the two metal centers in a spatial orientation and metal-metal fixed distance. The Au/Ru heterobimetallic complex is highly stable, easily accessible and exhibits promising catalytic activity in a visible-light mediated dual Au/Ru Meyer-Schuster rearrangement.
