摘要: Publisher Summary This chapter provides an overview of glycol-cleavage oxidation. Carbohydrates provide a profusion compounds that contain hydroxyl groups on two or more adjacent carbon atoms, and the fact this type carbon–carbon bond generally undergoes oxidative scission selectively quantitatively has been major factor contributing to current status carbohydrate chemistry. The periodate functions best in water leads tetra-acetate organic solvents, makes oxidation possible with all types carbohydrates derivatives. high selectivity lead tetraacetate as glycol-cleaving oxidants is attributed mainly ability central atom reagent complex 1,2-diol effect two-electron transfer. Formation intermediate shown for by pH ultraviolet spectral changes, and, both oxidants, less directly consideration reaction kinetics. action consistent concept five-membered ring than tetraacetate. characteristics oxidations are explained chapter. It also discusses properties glycosides related alicyclic explains patterns end-group analysis polysaccharides.
