Electrophilic amination is a chemical process involving the formation of a carbon–nitrogen bond through the reaction of a nucleophilic carbanion with an electrophilic source of nitrogen. [ 1 ] Introduction
A hydrogen on the α position of a carbonyl compound is weakly acidic and can be removed by a strong base to yield an enolate ion. In comparing acetone (pK a = 19.3) with ethane (pK a = 60), for instance, the presence of a neighboring carbonyl group increases the acidity of the ketone over the alkane by a factor of 10 40.
In organic chemistry, an azo coupling is an reaction between a diazonium compound (R−N≡N +) and another aromatic compound that produces an azo compound (R−N=N−R’).In this electrophilic aromatic substitution reaction, the aryldiazonium cation is the electrophile, and the activated carbon (usually from an arene, which is called coupling agent), serves as a nucleophile.
Cross electrophile coupling is a type of cross-coupling reaction that occurs between two electrophiles. It is often catalyzed by transition metal catalyst(s). Unlike conventional cross-coupling reactions of an electrophile with an organometallic reagent, [1] the coupling partners in cross electrophile coupling reactions are both electrophiles. [2]
A carbon atom with a larger coefficient will be preferentially attacked, due to more favorable orbital overlap with the electrophile. [ 16 ] The perturbation of a conjugating electron-withdrawing or electron-donating group causes the π electron distribution on a benzene ring to resemble ( very slightly !) an electron-deficient benzyl cation or ...
Oxymercuration reaction [1] In organic chemistry , the oxymercuration reaction is an electrophilic addition reaction that transforms an alkene ( R 2 C=CR 2 ) into a neutral alcohol . In oxymercuration, the alkene reacts with mercuric acetate ( AcO−Hg−OAc ) in aqueous solution to yield the addition of an acetoxymercury ( −HgOAc ) group and ...
Phosphorus trichloride is an inorganic compound with the chemical formula PCl 3. A colorless liquid when pure, it is an important industrial chemical , being used for the manufacture of phosphites and other organophosphorus compounds .
A major difference is that while silyl groups like the phenyldimethylsilyl group are converted to the hydroxy group after acid or other electrophile treatment followed by oxidation by hydrogen peroxide, disilanyl groups are converted after TBAF treatment followed by peroxide oxidation. This allows for selective oxidation of either group.
