During the reduction of N2 by V-nitrogenase at 30 degrees C, some hydrazine (N2H4) is formed as a product in addition to NH3 [Dilworth and Eady (1991) Biochem. J. 277, 465-468]. We show here the following. (1) That over the temperature range 30-45 degrees C the apparent Km for the reduction of N2 to yield these products is the same, but increases from 30 to 58 kPa of N2. On increasing the tempe...

Imatinib and its analogues were successfully synthesized by an improved method in 19.5– 46.2% total yield of six main steps. Pyrimidinyl amine was prepared by the reaction of enaminone and guanidine nitrate without the use of a toxic cyanamide. N-(2Methyl-5-nitrophenyl)-4-(pyridin-3-yl) pyrimidin-2-amine as a key intermediate for the synthesis of imatinib was prepared by coppercatalyzed N-aryla...

The possibility of electron binding to the HNNH3 and H2NNH2 tautomers of hydrazine was studied at the coupled cluster level of theory with single, double, and noniterative triple excitations. The HNNH3 tautomer, with a dipole moment of 5.4 D, binds an electron by 1076 cm-1 whereas the H2NNH2 tautomer forms neither a dipolenor valence-bound anionic state. It is suggested that the HNNH3 tautomer,...

ni6(n2h4)6(so4)4(oh)2(h2o)8](so4)(h2o)10 complex was prepared according to literature report. the reaction between aforementioned complex via sodium alkoxides as a reactants, were carried out in the solid state. the [ni6(n2h4)6(so4)4(oh)2(h2o)8](so4)(h2o)10 undergoes an intramolecular two electrons oxidation-reduction reaction at room temperature and metallic nickel nanoparticles (ni1-ni5) was ...

Successful implementation of molecular solution processing from a homogeneous and stable precursor would provide an alternative, robust approach to process multinary compounds compared with physical vapor deposition. Targeting deposition of chemically clear, high quality crystalline films requires specific molecular structure design and solvent selection. Hydrazine (N2H4) serves as a unique and...
