General procedure: The prepared grades of R-Ni were weighed in water after considering its specific gravity. The residual water was removed using dean stark apparatus. (0043) All the reactions were carried out in a 2-neck round bottom flask, attached with a condenser. Typically, reaction was carried out by stirring and refluxing the reaction mixture of amine and alcohol with pretreated R-Ni in 20ml solvent. After reaction completion, reaction mixture was cooled and filtered using Whatman filter paper 40. The solvent was removed in vacuo. The mixture thus obtained was purified using column chromatography. The purified compounds obtained were characterized by IR, NMR, LC-MS and melting or boiling point. The analytical data obtained of the known compounds are in agreement to the reported literature.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 3,5-Dibromo-1H-1,2,4-triazole, in my other articles.
