The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.10343-06-3, Name is 2,3,4,6-Tetra-o-acetyl-D-glucopyranose, molecular formula is C14H20O10. In a Article£¬once mentioned of 10343-06-3, SDS of cas: 10343-06-3
USE OF O-THALLIUM(I) SALTS IN THE SYNTHESIS OF PHOSPHATE, SULFITE, AND RELATED ESTER DERIVATIVES OF CARBOHYDRATES
O-Thallium(I) salts are shown to promote a variety of rapid, high-yield, substitution reactions at an anomeric, a primary, or a secondary position of carbohydrate derivatives.Synthesis are described of phosphates, phosphites, sulfites, and xanthic ester derivatives.Preparation of the thallous salt involves a facile exchange between thallous ethoxide and an alcohol group of the carbohydrate.The substitution reaction with the appropriate reagent (e.g., a phosphorochloridate) is then conducted in such solvents as benzene or acetonitrile, in which thallous salts are usually soluble.The configuration of an organo-phosphate moiety introduced at the anomeric position is strongly influenced by the choice of solvent, so that a preponderance of either the alpha- or beta-phosphate may be obtained.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 10343-06-3, you can also check out more blogs about10343-06-3
