Nitration and Sulfonation of Benzene - Chemistry LibreTexts
Web12 Apr 2024 · The single Fe and Pd sites could respectively catalyze nitrobenzene hydrogenation and styrene epoxidation, leading to a cascade synthesis of amino alcohols (Figure 12b). The detailed reaction mechanism was investigated by the control experiments ( Figure 12 c) and DFT calculations ( Figure 12 d), providing a versatile strategy to … Step 1: Nitric acid accepts a proton from sulphuric acid and then dissociates to form nitronium ion. Step 2: The nitronium ion acts as an electrophile in the process which further reacts with benzene to form an arenium ion. Step 3: The arenium ion then loses its proton to Lewis base forming nitrobenzene. See more Benzene reacts with concentrated nitric acid at 323-333K in the presence of concentrated sulphuric acidto form nitrobenzene. This reaction is known as nitration of benzene. See more Sulfonation of benzene is a process of heating benzene with fuming sulphuric acid (H2SO4 +SO3) to produce benzenesulfonic acid. The reaction is reversible in nature. See more Benzene reacts with halogens in the presence of Lewis acid like FeCl3, FeBr3to form aryl halides. This reaction is termed as halogenation of … See more WebReacting methylbenzene with a mixture of concentrated nitric and sulphuric acids gives both 2-nitromethylbenzene and 4-nitromethylbenzene. The mechanism is exactly the same as the nitration of benzene. You just have to be careful about the way that you draw the structure of the intermediate ion.
