Aqueous Persistent Noncovalent Ion-Pair Cooperative Coupling in a Ruthenium Cobaltabis(dicarbollide) System as a Highly Efficient Photoredox Oxidation Catalyst.

ABSTRACT: An original cooperative photoredox catalytic system, [Ru^II(trpy)(bpy)(H₂O)][3,3'-Co(1,2-C₂B₉H₁₁)₂]₂ (C4; trpy = terpyridine and bpy = bipyridine), has been synthesized. In this system, the photoredox metallacarborane catalyst [3,3'-Co(1,2-C₂B₉H₁₁)₂]^- ([1]^-) and the oxidation catalyst [Ru^II(trpy)(bpy)(H₂O)]²⁺ (C2') are linked by noncovalent interactions and not through covalent bonds. The noncovalent interactions to a large degree persist even after water dissolution. This represents a step ahead in cooperativity avoiding costly covalent bonding.
