The aromatizing ring-closing metathesis has been shown to take place inside an extended porous framework. Employing a combination of solvent-assisted linker exchange and postsynthesis modification using olefin metathesis, the noninterpenetrated SALEM-14 was formed and converted catalytically into PAH-MOF-1 with polycyclic aromatic hydrocarbon (PAH) pillars. The metal-organic framework in SALEM-14 prevents "intermolecular" olefin metathesis from occurring between the pillars in the presence of the first generation Hoveyda-Grubbs catalyst, while favoring the production of a PAH, which can be released from the framework under acidic conditions in dimethylsulfoxide.

-
Paragraph 0018-0025, (2019/03/25)
The invention discloses a sulfur-containing amino acid feed additive and a preparation method thereof, and belongs to the technical field of synthesis of feed additives. The key point of the technicalscheme of the invention is as shown in specification. Compared with the prior art, the sulfur-containing amino acid feed additive has the beneficial effects that the synthetic method is simple, a molecular structure is novel, and can react with nickel ions in a protein target of urease, the urease is inhibited to a certain extent, and the sulfur-containing amino acid feed additive is expected tobe further popularized and used as a composite feed additive.

Paragraph 0025; 0026; 0027; 0028; 0029; 0030, (2019/03/25)
The invention discloses a 3 - aldehyde - 4 - chloro pyridine of the preparation method, which belongs to the technical field of organic synthesis. Technical proposal of the invention points are: to pyridine as raw materials, the selective chlorination of at first, through the molecular distillation treatment to obtain a pure 4 - chloro pyridine, then in N, N - dimethyl formamide substitution reaction to obtain the 3 - aldehyde - 4 - chloro pyridine. The invention compared with the prior art has the following advantages: the invention synthetic method is simple, cheap price of raw materials, and is favorable for industrial production.

Page/Page column 50; 51, (2018/09/18)
Disclosed herein are compounds, compositions, and methods for reactivating or realkylating aged acetylcholinesterase inhibited by or conjugated to the organophosphorus compound. The organophosphorus compound can be a nerve agent. The acetylcholinesterase can be in the central nerve system (CNS) and/or the peripheral nervous system (PNS) of a subject. Accordingly, methods for ameliorating, diminishing, reversing, treating or preventing the toxic effects of an organophosphorus compound in a subject are provided herein. Methods for prophylactic or therapeutic treatment of exposure to an organophosphorus nerve agent are also provided.
