Application of 13273-53-5, New Advances in Chemical Research in 2021. The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic,A common heterocyclic compound, 13273-53-5, name is 4-Bromo-1-methyl-1H-1,2,3-triazole, molecular formula is C3H4BrN3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
General procedure: To a 50 mL round bottle flask was added 1,1?-Bis(diphenylphosphino)ferrocenedichloro Palladium(II) (0.1equiv), bromide (1.0equiv) and vinylboronic acid pinacol ester (2.0equiv) in 20mL dioxane. The mixture was degassed for 5min, and sodium carbonate aqueous solution (2.0M, 10equiv) was added. The mixture was then heated to 85C for 14h. After cooled to rt, the reaction mixture was filtered through a short Celite pad and washed with EtOAc. The organic solution was concentrated under reduced pressure and the residue was loaded into combi flush for purification to afford the product as oil.
In the meantime we’ve collected together some recent articles in this area about 13273-53-5 to whet your appetite. Happy reading!
