Synthetic Route of 16681-70-2, New Advances in Chemical Research in 2021.Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media, 16681-70-2, name is 1H-[1,2,3]Triazole-4-carboxylic acid, molecular formula is C3H3N3O2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
EXAMPLE 3 4,5-Dibromo-1H-1,2,3-triazole STR12 To a solution of 140 g (1.32 moles) of sodium carbonate in 650 ml of water was added 75 g (661 mmoles) of 1H-1,2,3-triazole-4-carboxylic acid. The resulting solution was subjected to the dropwise addition of 208 g (1322 mmoles) of bromine and then stirred overnight at room temperature. After cooling to 0 C., the reaction was adjusted to pH 4 with 12N hydrochloric acid causing precipitation of 147 g (98%) of 4,5-dibromo-1-H1,2,3-triazole as a white solid. The structure was confirmed by n.m.r. and I.R.
Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms.In my other articles, you can also check out more blogs about 1H-[1,2,3]Triazole-4-carboxylic acid.
