Nitrogen oxide (NOx) conversion is an important process for balancing the global nitrogen cycle. Distinct from the biological NOx transformation, we have devised a synthetic approach to this issue by utilizing a bifunctional metal catalyst for producing value-added products from NOx. Here, we present a novel catalysis based on a Ni pincer system, effectively converting Ni-NOx to Ni-NO via deoxygenation with CO(g). This is followed by transfer of the in situ generated nitroso group to organic substrates, which favorably occurs at the flattened Ni(I)-NO site via its nucleophilic reaction. Successful catalytic production of oximes from benzyl halides using NaNO2 is presented with a turnover number of >200 under mild conditions. In a key step of the catalysis, a nickel(I)-?NO species effectively activates alkyl halides, which is carefully evaluated by both experimental and theoretical methods. Our nickel catalyst effectively fulfills a dual purpose, namely, deoxygenating NOx anions and catalyzing C-N coupling.

Paragraph 0143-0144, (2021/04/10)
The present invention relates to a novel oxime derivative and application thereof in agriculture. The novel oxime derivative has a structure represented by formula (I), wherein R, R, R, R and R are each independently hydrogen, fluorine, chlorine or the like, A is shown as the specification, wherein R and R are each independently hydrogen, C1-4 alkyl group, phenyl group or the like, R is C1-4 alkoxy group or the like, and R is hydrogen or C1-4 alkyl group. The novel oxime derivative disclosed by the invention is novel in structure and simple in synthesis process, and has an excellent control effect on plant diseases, particularly cucumber downy mildew.

We report the synthesis of a vanadium(V) complex characterized by FT-IR and 1H NMR spectroscopy. The structure of the complex was established by single crystal X-ray crystallography. We also carried out the catalytic oxidation of benzyl alcohol, hetero-aryl alcohols and propargylic alcohols. Tandem synthesis of oximes from alcohols were also carried out using our vanadium(V) complex. The newly synthesized complex acts as a catalyst for oxidation reactions and tandem synthesis of oxime from alcohols.
