Catalyst bioinspired

The cationic complex [CpFe(CO)2(THF)]BF4 (23) can also catalyze the proton reduction from trichloroacetic acid by formation of Fe-hydride species and may be considered as a bioinspired model of hydrogenases Fe-H Complexes in Catalysis ) [44]. This catalyst shows a low overvoltage (350 mV) for H2 evolution, but it is inactivated by dimerization to [CpFe(CO)2l2-... 

The selective oxidation of alcohols to the corresponding aldehydes and ketones is of prime importance for organic synthesis, and various types of reagents have been described that achieve this transformation selectively and efficiently [141,142]. However, the number of sub-stoichiometric, nontoxic, non-hazardous oxidation systems has been relatively Umited. As copper enzymes such as galactose oxidase are known to catalyze this oxidation reaction, bioinspired homogeneous catalysts based on copper species have also been developed in recent years.

Next, there was a technical session on robust implementation of bioinspired catalysts, which included the following topics and speakers Mimicking Photosynthetic Energy Transduction, Thomas Moore, Arizona State University Biological Transformations for Energy Production An Overview of Biofuel Cells, G. Tayhas Palmore, Brown University and Bioinspired Initiatives at DuPont, Mark Emptage, DuPont. Open discussion was then moderated by Leonard Buckley. 

Speakers addressing robust implementation responded to the following questions How can bioinspired design principles be replicated in synthetic and semisynthetic catalysts and catalytic processes Can discovery methods (e.g., bioinformatics) be harnessed to encode designer catalytic sites To what extent can protein scaffolds be replicated with more easily synthesized supports, and can we use these principles to design sequential catalytic assemblies ...
