Learn about reagents in chemistry and understand how they are used. Compare reagent vs. reactant characteristics and discover examples of each of...
Reagent Examples Reagents may be compounds or mixtures. In organic chemistry, most are small organic molecules or inorganic compounds. Examples of reagents include Grignard reagent, Tollens' reagent, Fehling's reagent, Collins reagent, and Fenton's reagent. However, a substance may be used as a r...
This review is focused on the achievements of divergent catalysis with the simplest substrates in the past decades. It includes divergent catalysis of one-component and two-component reactions with the same and simple reagents, ranging from carbon-carbon-forming pinacol coupling, benzoin condensation, ...
solid-phase synthesis. The principal difference is that synthesis occurs in solution or liquid-phase (i.e. NOT fixed to any surface). As this process still proceeds in cycles, there are several accompanying methods for removal of unreacted reagents while retaining the elongated oligonucleo...
we exclude reagents containing bh, nh, oh, sih, ph or sh groups or aromatic n, s or sulfide, disulfide, sulfoxyde or sulfimide groups and we also exclude aldehydes producing carboxylic acids with these reagents. refer to the chemical terms reference tables for chemaxon's chemical terms ...
(1) physical separation by temporarily converting the two enantiomers into two diastereomers (called resolution); (2) physical separation in a chiral chromatographic environment; (3) chemical discrimination in a chiral environment (using enzymes or other chiral platforms as chemical reagents ); and (...
Chemical kinetics is the division of physical chemistry that deals with the rates of a chemical reaction as well as the pathways through which a chemical reaction occurs. There are many factors which affect the rate of chemical reaction, catalyst is one of them....
No alpha hydrogen atom is available in the case of tertiary alcohols. The reagents used for oxidation are also different. The most common mild oxidizing agents used are Jones' reagent- acidified potassium or sodium dichromate solution- hypochlorous acid or pyridinium chlorochromate. When treated with...
The more electron-rich a nucleophile is the better it reacts in organic synthesis. Some examples include hydroxides, amines, alkoxides, phosphines, azides, nitrites, iodide, cyanide, acetylide, Grignard's reagents, organolithium reagents, organocuprate reagents, and hydrides. How do you identify ...
9. Catalytic reagents (as selective as possible) are superior to stoichiometric reagents. 10. Chemical products should be designed so that at the end of their function they do not persist in the environment and break down into innocuous degradation products. ...
