The catalytic hydrogenation of prochiral ketones with second and third-row transition metal complexes bearing chelating chiral ligands containing at least one N–H functionality has achieved unparalleled performance, delivering, in the best cases, chiral alcohols with up to 99.9% ee using extremely smal...
The reduction proceeds by a thiophilic addition of HSon the thioketone most likely via a single electron transfer mechanism.关键词: NADH mimics synthesis asymmetric reduction semi-empirical calculation DOI: 10.1016/S0040-4039(97)10572-X 被引量: 2 ...
The results of cyclic voltammetric studies are consistent with a mechanism involving reversible reduction of the α,β-unsaturated ketone to its radical anion followed by irreversible dimerization. 展开 被引量: 2 年份: 1971 收藏 引用 批量引用 报错 分享 ...
There is a break in the carbon chain on oxidation. A mixture of carboxylic acids is the product. The carboxylic acids have fewer carbon atoms than the original ketone. What is the difference between aldehydes and ketones? Aldehydes have a carbon attached to an alkyl or aryl group, an oxygen...
Carbon fibers are widely used as reinforcements in poly-ether-ether-ketone (PEEK). In recent years, these materials have also been used for tribological applications. For further optimization of these tribo-materials, the contribution and action mechanisms of carbon fiber reinforcements to the tribolog...
The Wolff-Kishner reduction has two main stages in the mechanism. The substitution of the hydrazine for the ketone to form a hydrazone. Then the reduction of the carbon-nitrogen double bond into hydrocarbons. Which catalyst is used for the Wolff-Kishner reduction? None of the reactants are te...
