On August 14, 2018, Mercado, Rocio; Fu, Rueih-Sheng; Yakutovich, Aliaksandr V.; Talirz, Leopold; Haranczyk, Maciej; Smit, Berend published an article.Safety of 3,6-Dibromopyrazine-2,5-dicarbonitrile The title of the article was In Silico Design of 2D and 3D Covalent Organic Frameworks for Methane Storage Applications. And the article contained the following:

We present a database of 69,840 largely novel covalent organic frameworks assembled in silico from 666 distinct organic linkers and 4 established synthetic routes. Due to their light weights and high internal surface areas, the frameworks are promising materials for CH4 storage applications. To assess their CH4 storage performance, we used grand-canonical Monte Carlo simulations to calculate their deliverable capacities. We demonstrate that the best structure, composed of C-C bonded triazine linkers in the tbd topol., has a predicted 65-bar deliverable capacity of 216 v STP/v, better than the best CH4 storage materials published to date. Using our approach, we also discovered other high-performing materials with 300 structures with calculated deliverable capacities >190 v STP/v and 10% of these outperforming 200 v STP/v. To encourage screening studies of these materials for other applications, all structures and their properties were made available on the Materials Cloud. The experimental process involved the reaction of 3,6-Dibromopyrazine-2,5-dicarbonitrile(cas: 1391026-27-9).Safety of 3,6-Dibromopyrazine-2,5-dicarbonitrile

On May 18, 2017, Yasuda, Takuma; Park, In Seob; Yang, Yu Seok; Sumiya, Hiroshi; Fukushima, Yukio published a patent.Category: pyrazines The title of the patent was Dicyanopyrazine compound, luminescent material for light transmitter, and preparation method for 2,5-dicyano-3,6-dihalogenopyrazine. And the patent contained the following:

Dicyanopyrazine compound I [R3 = electron-donating group; R4 = H, (un)substituted aryl or electron-donating group; L3 = (un)substituted heteroarylene or (un)substituted arylene; L4 = single bond, (un)substituted heteroarylene or (un)substituted arylene; L3 and L4, together with carbon atoms to which each is attached, may combine to form a ring] and II [R5 = electron-donating group; R6 = H, (un)substituted aryl or electron-donating group; L5 = (un)substituted heteroarylene or (un)substituted arylene; L6 = single bond, (un)substituted heteroarylene or (un)substituted arylene] were provided. Organic electroluminescent device comprising an invention compound, e.g., III, showed maximum external quantum efficiency of higher than 5%. Further disclosed is a preparation method of 2,5-dicyano-3,6-dihalogenopyrazine. For example, treatment of 2,3-diamino-3-(phenylthio)acerylonitrile with citric acid-sodium citrate buffer (pH = 3.0) [1,2-dimethoxyethane, water, room temperature, 5 h, 45%] and halogenation [CuBr2, tert-Bu nitrite, acetonitrile, 70°, 5 h] afforded 2,5-dicyano-3,6-dibromopyrazine (67.0% yield). Of note, 2,5-dicyano-3,6-dihalogenopyrazine is a useful synthetic intermediate for dicyanopyrazine compound The experimental process involved the reaction of 3,6-Dibromopyrazine-2,5-dicarbonitrile(cas: 1391026-27-9).Category: pyrazines
