Intermediate complexes in chemical and biological nitrogen fixation

Mechanism of dinitrogen reduction in protic media is discussed in the light of results obtained for specially prepared binuclear complexes M"M with bridging dinitrogen capable to be protonated and reduced. The conclusion is made that such complexes with d2 or d3 electronic configuration of M together with additional electron donor are likely intermediates in catalytic dinitrogen reduction by co...

Chemical nitrogen fixation by using molybdenum and tungsten complexes*

Dinitrogen complex cis-[W(N2)2(PMe2Ph)4] reacts with an excess of acidic dihydrogen complexes such as trans-[RuCl(η-H2)(dppe)2]BF4 (dppe = 1, 2-bis(diphenylphosphino)ethane) at 55 °C under 1 atm of H2 to form ammonia in moderate yield. The reaction is presumed to proceed through nucleophilic attack of the remote nitrogen of the coordinated dinitrogen on the dihydrogen ligand. The coordinated di...

Biological nitrogen fixation, 1924-1974.

Crop rotation was practiced in ancient times by alternating the use of leguminous and nonleguminous plants. The basis for the benefit derived from this practice was not understood, but it was observed empirically that crops were improved and the condition of the soil was maintained better with rotation than by continual cropping with nonleguminous plants. Rotation was recognized as good husband...

“Biological Nitrogen Fixation” Book Summary

Biological nitrogen fixation is a very valuable alternative to nitrogen fertilizer. This process will be discussed in the “Biological Nitrogen Fixation” book. A wide array of free-living and associative nitrogen fixing organisms (diazotrophs) will be covered. The most extensively studied and applied example of biological nitrogen fixation is the symbiotic interaction between nitrogen fixing “rh...

Mechanism of Biological Nitrogen Fixation

Recently Phelps and Wilson (1) reported the occurrence of hydrogenase, the enzyme which activates molecular hydrogen, in nitrogen-fixing bacteria. Because HZ specifically inhibits nitrogen fixation by red clover plants inoculated with Rhizobium trijolii as well as by Azotobacter (2,3), possession of hydrogenase by these organisms may be more than merely fortuitous. The possibility must be consi...
