Kurzfassung:
Nitrous oxide (N 2 O) reduction is a chemical challenge both in the selective oxidation of organic substrates by N 2 O and in the removal of N 2 O as a green‐house gas. The reduction of N 2 O is thermodynamically favorable but kinetically inert, and requires activating transition‐metal centers. In biological systems, N 2 O reduction is the last step in the denitrification process of the bacterial nitrogen cycle and is accomplished by the enzyme nitrous oxide reductase, whose active site consists of a μ 4 ‐sulfide‐bridged tetranuclear Cu Z cluster which has many unusual spectroscopic features. Recent studies have developed a detailed electronic‐structure description of the resting Cu Z cluster, determined its catalytically relevant state, and provided insight into the role of this tetranuclear copper cluster in N 2 O activation and reduction.
