aBoth of the alcohol functional groups of 84 were oxidized using a Dess-Martin oxidation in 90% yield and the resulting sulfone was removed via a reductive cleavage upon reaction with SmI2 to give ketoaldehyde 85 in 85% yield. 两个酒精功能小组84使用Dess马丁氧化作用在90%出产量被氧化了,并且...
functional group, any of numerous combinations of atoms that form parts of chemical molecules, that undergo characteristic reactions themselves, and that in many cases influence the reactivity of the remainder of each molecule. In organic chemistry the concept of functional groups is useful as a basi...
Three classes of molecules are examined: alkoxy radicals with saturated hydrocarbon backbones, those with alcohol functional groups, and those with carbonyl functional groups. The chosen species represent many of those found during the combustion of fossil fuels as well as bio-derived alternatives. ...
Alcohol –OH R3C–OH CH3–OH (methanol) Phenol –OH Ar*–OH C6H5–OH (phenol) In contaminants, the hydroxyl group is present in two broad classes of compounds: (a) Alcohols: Organic compounds where an –OH– group is bound to a saturated carbon atom (i.e., the central carbon atom...
Chemical transformations that introduce, remove or manipulate functional groups are ubiquitous in synthetic chemistry1. Unlike conventional functional-group interconversion reactions that swap one functionality for another, transformations that alter sol
The invention relates to poly(vinylalcohol)-co-poly(vinylamine) copolymers represented as formula (I), where B is greater than or equal to 1, L is independently of each other a chemical linking group which is -NH-, -N-, >N-, >N++<, -O- or -CO-, COPOLYMER is derived from a pr...
CONCLUSION Lifestyle-related characteristics mainly accounted for the association between moderate alcohol intake and lower risk of functional decline over time. These findings do not support a direct causal effect of alcohol intake on physical function. 展开 关键词: alcohol intake functional decline ...
The adsorption energies for the alcohols are typical of chemisorption and indicate alcohol displacement of water from calcium carbonate surfaces. This explains why organisms favor biomolecules that contain alcohol functional groups (-OH) to control which polymorph they use, the crystal face and ...
