The diprotonated species is reduced in a two-electron process involving an ECE mechanism. In more dilute solutions of sulfuric acid the diprotonated species is formed in an acid catalyzed dehydration. The rate determining step involves protonation of the pyridiniumcarboxaldehyde geminal diol, followed ...

While the oxidation of a wide variety of alcohols by ADH has been investigated extensively, the reduction of aldehydes and ketones has received much less attention even though the equilibrium favors the latter process. For each isozyme, the Km and kcat values were measured at pH 7.0 with acetal...
Learn about aldehydes and ketones. Understand oxidation and reduction of aldehydes and ketones and how both aldehydes and ketones produce cyanohydrin.
The catalytic activity of Gd(i-PrO)3 is about 103 times as high as that of Al(i-PrO)3. Compared with Gd(i-PrO)3, Yb(i-PrO)3 is less active for the reduction of ketones but is efficient for that of aldehydes.关键词: reduction, hydrogenation ...
