Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. , Quality Control of 2-Iodoacetamide, 144-48-9, Name is 2-Iodoacetamide, molecular formula is C2H4INO, belongs to iodides-buliding-blocks compound. In a document, author is Chen Liyuan, introduce the new discover.
Function of Potassium Iodide in the Reaction of 1,2-Bis-(dibromomethyl)benzene and Its 4-Substituted Derivatives with Fumaronitrile
1,2-Bis(dibromomethyl)benzene and its 4-substituted derivatives would not react with fumaronitrile in N,N-dimethylformamide in the absence of potassium iodide. However, the same reaction happened in the presence of potassium iodide. The major product was 2,3-dicyanonaphthalene or its corresponding substituted derivatives. The yields depended on the adding amounts of the potassium iodide. When the adding amount of potassium iodide was equal to the molar amount of bromine atoms in 1,2-bis(dibromomethyl)benzene or its 4-substituted derivatives, the reaction was substantially completed and the main product was 2,3-dicyanonaphthalene or its corresponding substituted derivatives with yield of 87.1%. Based on this fact, the function of potassium iodide was not a catalyst but a reaction reagent, and the reaction mechanism was proposed.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 144-48-9. Quality Control of 2-Iodoacetamide.
