Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. , Category: iodides-buliding-blocks, 19094-56-5, Name is 2-Chloro-5-iodobenzoic acid, molecular formula is C7H4ClIO2, belongs to iodides-buliding-blocks compound. In a document, author is Schmid, U, introduce the new discover.
O-glycoside synthesis with glycosyl iodides under neutral conditions in 1 M LiClO4 in CH2Cl2
Glycosyl phosphates, imidates, trifluoroacetates, chlorides, and bromides are converted into the respective glycosyl iodides by treatment with LiI or NaI in 1 M solutions of LiClO4 in CH2Cl2. Under these neutral conditions the reactive glycosyl iodides are activated, and react with different glycosyl acceptors to give O-glycosides in moderate yields, with the alpha-anomers predominating. The glycosylation reactions most probably proceed by the initial formation of beta-configured glycosyl iodides from the alpha-configured precursors, and subsequent attack of the glycosyl acceptor on the equatorial iodide from the axial direction.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 19094-56-5. Category: iodides-buliding-blocks.
