Reduction of a tris(picolyl)amine copper(ii) complex by a polymeric flavo-reductase model in water.

Dioxygen activation at copper(i) centres is of primary importance for the development of sustainable oxidation catalysis, but regeneration of copper(i) centres after each catalytic cycle remains a major problem for multi-turn-over catalysis. This work demonstrates that an artificial reductase, made of flavin cofactors incorporated into a water soluble polymer, efficiently reduces a Cu(ii)TPA complex in the presence of NADH in water.
