Fungal denitrification plays a crucial role in the nitrogen cycle and contributes to the total N2O emission from agricultural soils. Here, cytochrome P450 NO reductase (P450nor) reduces two NO to N2O using a single heme site. Despite much research, the exact nature of the critical “Intermediate I” responsible for the key N-N coupling step in P450nor is unknown. This species likely corresponds to a Fe-NHOH-type intermediate with an unknown electronic structure. Here we report a new strategy to generate a model system for this intermediate, starting from the iron(III) methylhydroxylamide complex [Fe(3,5-Me-BAFP)(NHOMe)] (1), which was fully characterized by 1H NMR, UV-vis, electron paramagnetic resonance, and vibrational spectroscopy (rRaman and NRVS). Our data show that 1 is a high-spin ferric complex with an N-bound hydroxylamide ligand that is strongly coordinated (Fe-N distance, 1.918 A Fe-NHOMe stretch, 558 cm-1). Simple one-electron oxidation of 1 at -80 C then cleanly generates the first model system for Intermediate I, [Fe(3,5-Me-BAFP)(NHOMe)]+ (1+). UV-vis, resonance Raman, and Moessbauer spectroscopies, in comparison to the chloro analogue [Fe(3,5-Me-BAFP)(Cl)]+, demonstrate that 1+ is best described as an FeIII-(NHOMe)? complex with a bound NHOMe radical. Further reactivity studies show that 1+ is highly reactive toward NO, a reaction that likely proceeds via N-N bond formation, following a radical-radical-type coupling mechanism. Our results therefore provide experimental evidence, for the first time, that an FeIII-(NHOMe)? electronic structure is indeed a reasonable electronic description for Intermediate I and that this electronic structure is advantageous for P450nor catalysis because it can greatly facilitate N-N bond formation and, ultimately, N2O generation.

The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules.

The topic of intermolecular interactions enhancing electron tunneling between protein residues on biofilm surface has been investigated by some theoretical studies. However, few of experimental studies could confirm this viewpoint. In this work, the Mercaptopropionic acid self-assembled monolayer (MPA SAM) with terminal carboxyl groups was constructed, as a simplified model for functionalized biomimic membrane. The electron tunneling rate constant of ferrocenylmethanol redox process on SAM was obtained from experimental results of scanning electrochemical microscopy. It is found that the electron tunneling across MPA SAM is faster than that of contrastive Methyl mercaptopropionate SAM. This result is attributed to the intermolecular interactions between the redox and MPA molecules. The conditions of lower pH and weaker ion pair effect all benefit the formation of the intermolecular interactions, resulting the enhancement of electron tunneling more obvious. Based on this, this kind of intermolecular interaction is inferred to be intermolecular hydrogen bond. Our work may have contributions to exploring electron tunneling between protein residues on biofilm surface.

A typical Chinese liquor was characterised using a triple-electrode system with clean and simple design. In this approach, liquors were analysed with no other pre-treatment than mixing the liquor with a potassium chloride solution to ensure sufficient conductivity. Two broad reduction peaks at [?0.3 V, ?0.5 V] and [?0.7 V, ?0.8 V] were present in the cyclic voltammetry, demonstrating the feasibility of the gold electrode for liquor characterisation. Both the competing reactions in the liquor samples contributed to the reduction current. Thus, the steady-state microelectrode voltammetry affords an opportunity to estimate the total concentration of the redox-active species in the mixed compounds according to the relationship between the total concentration and the value of limiting diffusion current. Further, the discrimination of liquors at different ageing times was realised by the conjunction of the electrochemical results and principal component analysis.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis. We will look forword to the important role of 1273-86-5, and how the biochemistry of the body works.SDS of cas: 1273-86-5

Acetylferrocene, cas is 1271-55-2,the iron-catalyst compound, it is a common compound, a new synthetic route is introduced below.

General procedure: A solution of pure TsNHNH2 (15 mmol) in methanol (30 mL) was stirred and heated to 60 C until the TsNHNH2 dissolved. The mixture was cooled to room temperature. Then a solution of ferrocenylketone (10 mmol) in methanol was dropped into the mixture slowly. After approximately 0.5-2 h, the crude products could be obtained as solid precipitate. The precipitate was washed with petroleum ether then removed in vacuo to give the pure products. In general, the yields were 68-86 %.
