Webb1. SO 3 and H 2 SO 4 (fuming) 2. 3. Sulfuric acid is needed in order for a good electrophile to form. Sulfuric acid protonates nitric acid to form the nitronium ion (water molecule is lost). The nitronium ion is a very good electrophile and is open to attack by benzene. Without sulfuric acid the reaction would not occur. 4. WebbElectrophilic nitration of toluene and benzene was studied under various conditions with several nitrating systems. It was found that high orthopara regioselectivity is prevalent in all reactions and is independent of the reactivity of the nitrating agent. The methyl group of toluene is predominantly ortho-para directing under all reaction conditions.
Webb29 jan. 2016 · A series of benzo[c]chromen-6-ones are prepared by a Suzuki coupling and lactonization sequence starting with 2-methoxyphenylboronic acids and methyl 2-bromobenzoate derivatives. WebbNitration of Mechanism. Since most of the examples listed above are benzene derivatives, we shall discuss the mechanism of benzene nitration. The nitronium ion (NO 2 +) present in the mixture is the active species that attacks the organic compound to form an unstable complex.The nitrated hydrocarbon is formed when a proton is removed from the …
Webb1. Source of nitronium ion- nitric acid is not a sufficient electrophile alone. But with sulfuric acid, it is strong enough. 2. Polysubstitution- once the bromobenzene reacts with one nitronium ion, it cant react with another. To prevent this polysubstitution, the temp is kept below a certain mark. The activation energy of the polysubstitution ...
