... Much of bridging CO group, and a pseudo-octahedral iron with open their reactivity beyond use as transfer hydrogenation cata site blocked by a strategically positioned arene group from lysts remains relatively unexplored. The metal diamido com the bulky NHC carbene ligand (Peters et al., 1998; Nicolet et plexes behave as a dehydrogenase-related catalyst toward al., 1999)

We have acquired a number tural models do not contain the unique "rotated" or entatic of special nickel-thiolate compounds that replicate some state that is the consensus structure of the enzyme active site of the unusual structural and electronic and redox proper- (eas) in its resting state.1 As demonstrated by 13C VT NMR ties of the Ni center in hydrogenases, including series of studies the minimal model of the eas, (µ-pdt)

Muckerman1 1 Chemistry Department, Brookhaven National Laboratory, Upton, NY 11973-5000, USA OC S O 2 Institute for Molecular Science and CREST, 5-1 Higashiyama, ­Myodaiji, S C Okazaki, Aichi 444-8787, Japan Fe Fe OC CO OC CO NAD+/NADH is one of the most important redox ground state mediators in biological systems, including photosystem I, structure of mode and acts as a reservoir/source of two electrons and a proton. A polypyridylruthenium complex with an NAD+ functional A-2.eps model ligand investigated here is the first example that an NAD+/NADH model complex works as a catalytic hydride donor for chemical reactions such as the electroreduction of acetone to 2-propanol (Koizumi and Tanaka, 2005)
