The mixture was then concentrated and evaporated to dryness. Toluene (15mL) was added to the residue, the precipitate (product) was filtered, washed with water on the filter and dried. The off-white powder-like material was dissolved in methanol, the palladium-black was filtered off and methanol was evaporated.

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 4H-1,2,4-Triazol-4-amine, in my other articles.
