Chemistry, like all the natural sciences, begins with the direct observation of nature— in this case, of matter. 28244-94-2, Name is 4-Methylphenyl 2,3,4,6-tetra-O-acetyl-1-thio-β-D-glucopyranoside, molecular formula is C21H26O9S. In a Article，once mentioned of 28244-94-2, COA of Formula: C21H26O9S
Electrochemical properties of various para-substituted phenylthio-, phenylseleno-, and phenyltelluroglucopyranosides bearing acetyl, benzoyl, and benzyl protecting groups have been investigated to estimate the reactivity of chalcogenoglycosides toward electrochemical glycosylations. The oxidation potential of the chalcogenoglycosides shows good correlation with the ionization potential of chalcogen atoms, and decreases in the order thio-, seleno-, and telluroglycosides. It is also affected by the para-substituents, and the substitution effect correlates very well with the HOMO energy of para-substituted benzenechalcogenol and with the Hammett sigmap+ value. Electrochemical glycosylation of telluroglycosides has been examined, and it was found that the use of an undivided cell is more effective than the use of a divided cell. Selective activation of the chalcogenoglycosides in bulk electrolysis based on their oxidation potentials has been examined, and the relative reactivity of the telluroglycosides can be estimated from their oxidation potentials. However, the relative reactivity of selenoglycosides in the preparative glycosylation was rather insensitive to the oxidation potential values.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.COA of Formula: C21H26O9S, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 28244-94-2, in my other articles.
