WebbNitration is used to add nitrogen to a benzene ring, which can be used further in substitution reactions. The nitro group acts as a ring deactivator. Having nitrogen present in a ring is very useful because it can be used as a directing group as well as a … Nitration can be accelerated by activating groups such as amino, hydroxy and methyl groups also amides and ethers resulting in para and ortho isomers. The direct nitration of aniline with nitric acid and sulfuric acid , according to one source, [11] results in a 50/50 mixture of para - and meta -nitroaniline isomers. Visa mer 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 Visa mer Typical nitration syntheses apply so-called "mixed acid", a mixture of concentrated nitric acid and sulfuric acids. This mixture produces the 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 … 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 alternative products act as contaminants or are simply wasted. Accordingly, it is desirable to design syntheses with … Visa mer • Menke nitration • Zincke nitration • Reactive nitrogen species Visa mer
