Synthesis, structure, and 15N NMR studies of paramagnetic lanthanide complexes obtained by reduction of dinitrogen.
The recently discovered LnZ3/M and LnZ2Z'/M methods of reduction (Ln = lanthanide; M = alkali metal; Z, Z' = monoanionic ligands that allow these combinations to generate "LnZ2" reactivity) have been applied to provide the first crystallographically characterized dinitrogen complexes of cerium, [C5Me5)2(THF)Ce]2(mu-eta2.eta2-N2) and [(C5Me4H)2(THF)Ce]2(mu-eta2.eta2-N2), so that the utility of 1...
متن کامل15N and 31P NMR Studies of Cyano[(Trialkyl/Triaryl)Phosphine]Gold(I) Complexes R3PAu13C15N
been studied for R=Me, Et, i-Pr, and Ph. The reactions are studied by 15N and 31p NMR spectroscopy. Two 31p NMR resonances were observed for R3PAuCN and (R3P)2Au+ species. However, for the 15N NMR, only averaged resonances were observed for R3PAuC15N and Au(C15N)2" species except for Et3PAuC15N, where two resonances were detected.The R3PAu13C15N complexes have also been prepared where R= Me, Et...
متن کامل15N-NMR Study on Complexes of Low-Spin F erritetraphenylporphyrin
l5N-NM R chemical shifts, spin-lattice, and spin-spin relaxation times of the four pyrrole nitro gen nuclei in complexes o f low-spin ferritetraphenylporphyrin with pyridine and 1-methylimidazole in chloroform have been studied. Although deviations from an axial symmetry are observed at 4K by EPR and ENDOR spectroscopy, only one 15N-NM R absorption signal can be detected at T < 200 K indicatin...
متن کاملCell-free synthesis of 15N-labeled proteins for NMR studies.
Modern cell-free in vitro protein synthesis systems present powerful tools for the synthesis of isotope-labeled proteins in high yields. The production of selectively 15 N-labeled proteins from 15 N-labeled amino acids is particularly economic and yields are often sufficient to analyze the proteins very quickly by two-dimensional NMR spectra recorded of the crude reaction mixture without concen...
متن کاملGlutamate biosynthesis in Bacillus azotofixans. 15N NMR and enzymatic studies.
Pathways of ammonia assimilation into glutamic acid in Bacillus azotofixans, a recently characterized nitrogen-fixing species of Bacillus, were investigated through observation by NMR spectroscopy of in vivo incorporation of 15N into glutamine and glutamic acid in the absence and presence of inhibitors of ammonia-assimilating enzymes, in combination with measurements of the specific activities ...
