In organic chemistry, nitration is a general class of chemical processes for the introduction of a nitro group (−NO2) into an organic compound. The term also is applied incorrectly to the different process of forming nitrate esters (−ONO2) between alcohols and nitric acid (as occurs in the synthesis of … Visa mer Typical nitration syntheses apply so-called "mixed acid", a mixture of concentrated nitric acid and sulfuric acids. This mixture produces the nitronium ion (NO2 ), which is the active species in aromatic nitration. This active … Visa mer • Menke nitration • Zincke nitration • Reactive nitrogen species Visa mer Selectivity can be a challenge in nitrations because as a rule more than one compound may result but only one is desired, so … Visa mer With aryl chlorides, triflates and nonaflates, ipso nitration may also take place. The phrase ipso nitration was first used by Perrin and Skinner in 1971, in an investigation into chloroanisole nitration. In one protocol, 4-chloro-n-butylbenzene is reacted with Visa mer

WebbUpon treatment with a weak electrophile (carbon dioxide), it undergoes electrophilic substitution reaction to form Ortho-hydroxybenzoic acid. This reaction is popularly known as Kolbe’s reaction. 4. Reimer-Tiemann Reaction. When phenol is treated with chloroform in the presence of sodium hydroxide, an aldehyde group is formed at the ortho ... WebbThe nitration of methylbenzene (toluene) Methylbenzene reacts rather faster than benzene - in nitration, the reaction is about 25 times faster. That means that you would use a lower temperature to prevent more than one nitro group being substituted - in this case, 30°C rather than 50°C.
