Carbonyl isomerization
WebDec 27, 2024 · Carbonyl isomerization is involved in the metabolism of carbohydrates (starches and sugars) to their eventual conversion to CO 2 and H 2 O. First, starches are broken down into glucose in the digestive tract. In the cells, the first step of the glycolysis pathway involves an enzyme converting glucose to glucose-6-phosphate. WebOur mechanistic data indicate that a Ni(I)dimer is formed under these conditions, which serves as a catalyst resting state and, upon reaction with an alkyl bromide, is converted to [Ni(II)-H] as an active chain-walking/functionalization catalyst, ultimately generating a stabilized η3-bound Ni(II)enolate as the key selectivity-controlling …

WebFeb 18, 2015 · If our substituent is an alkyl group (X=R, an imine), the carbon is less electronegative then nitrogen, there will be increased electron density in the nitrogen orbital used to form the N − R bond. The nitrogen will hybridize such that there is more s character in this orbital so as to better stabilize these electrons. http://polymerdatabase.com/polymer%20chemistry/Carbonyl%20Polymerization.html
