A simple and efficient strategy for constructing nitrogen-rich isomeric salts and cocrystal through pK(a) calculation
Nitrogen-rich energetic salts and cocrystal have attracted considerable attention in recent years. To assess the formation of cocrystal or salt, acid dissociation constant (pK(a)) values of the isomeric co-formers were calculated in this work and significant differences were observed. Two salts and one cocrystal based on H2BT (1H, 1’H-5,5′-bitetrazole), DATr (4,5-diamino-4H-1,2,4-triazole), 1MAT (1-methyl-5-aminotetrazole) and 2MAT (2-methyl-5-aminotetrazole) were synthesized, which corresponding to the different pK(a) values of three isomeric coformers. Single crystal structure analysis reveals that all compounds are formed by layered stacking structure with pi-pi stacking and rich hydrogen bonds, resulting in the insensitivity towards impact and friction (impact sensitivity > 40 J, friction sensitivity > 360 N). To the best of our knowledge, it is the first time to report the cocrystal of H2BT. The study results provide a utility method to seek for suitable coformers and design energetic cocrystal through the calculation of pK(a). (C) 2020 Elsevier B.V. All rights reserved.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 5232-99-5 is helpful to your research. Recommanded Product: Ethyl 2-cyano-3,3-diphenylacrylate.
