Nickel-Catalyzed Cyanation of Aryl Thioethers

, p. 7018 - 7022 (2021)
A nickel-catalyzed cyanation of aryl thioethers using Zn(CN)2 as a cyanide source has been developed to access functionalized aryl nitriles. The ligand dcype (1,2-bis(dicyclohexylphosphino)ethane) in combination with the base KOAc (potassium acetate) is essential for achieving this transformation efficiently. This reaction involves both a C-S bond activation and a C-C bond formation. The scalability, low catalyst and reagents loadings, and high functional group tolerance have enabled both late-stage derivatization and polymer recycling, demonstrating the reaction's utility across organic chemistry.

Abstract: A new series of 1,3,4-oxadiazole derivatives with a 3-chloropyridin-2-yl-1H-pyrazole moiety was designed, synthesized, and characterized. The results of bioassay against Helicoverpa armigera and Plutella xylostella indicated that some of the synthesized compounds showed remarkable larvicidal activity. In particular, the LC50 values of the most active compounds against P. xylostella were 46.5, 23.9, and 13.9?mg/dm3, and against Helicoverpa armigera were 88.3 and 69.5?mg/dm3, the latter being slightly better than commercial chlorpyrifos (LC50 103.77?mg/dm3). Preliminary SAR was also discussed. Graphical abstract: [Figure not available: see fulltext.].
Tirfluoromethylpyridine oxadiazoles (ether)derivative and application thereof
-
Paragraph 0120-0124, (2018/07/30)
The invention discloses an application of a tirfluoromethylpyridine oxadiazole (ether)derivative in a pesticide. A structure is shown as a general formula I, a compound shown in the general formula Ihas good insecticidal activity, and can be used for controlling insects such as diamondback moth and armyworm. The compound has excellent control effect for insects such as diamondback moth and armyworm, and also has control effect for the insects having resistance to the traditional pesticides, in addition, introduction of fluorine-containing groups such as tirfluoromethylpyridine and oxadiazoleas well as heterocyclic ring can enhance a rate for forming hydrogen bond effect between a compound and a target, and the activity of the compound is increased.

, p. 337 - 342 (2008/09/18)
A reliable and high-yielding one-pot sequence for the removal of O-carboxymethyl moieties from phenols is presented. When diethylphosphoryl azide is employed as the azide transfer reagent in the Curtius rearrangement and glycerol in the subsequent hydrolytic workup, the protocol can be reliably applied to a very broad scope of substrates.
