WebThe Halogenation of Benzene. Halogenation is an example of electrophillic aromatic substitution. In electrophilic aromatic substitutions, a benzene is attacked by an electrophile which results in substition of hydrogens. However, halogens are not electrophillic enough to break the aromaticity of benzenes, which require a catalyst to activate.
Nucleophilic Reactions of Benzene Derivatives
WebIn the direct chlorination of ethylene 1,2-DCE is obtained by the reaction of ethylene and chlorine in liquid dichloroethane under pressure of 3-4 bar at 120-125 °C in the presence of FeCl3 as catalyst and NaCl as promoter according to the following scheme [1]: CH2=CH2 + Cl2 + FeCl3 ® ClCH2–CH+2 + FeCl -4 ® ClCH2CH2Cl + FeCl3. WebThe chlorination of benzene with FeCl3/Cl2 proceeds through a Lewis acid- base complex between FeCl3 and Cl2. 1) A mechanism can be drawn in which FeCl3 and Cl2 react to form the Cl+ cation. This doesn’t happen but is sometimes incorrectly shown in some sources. Draw that mechanism. mail boat to bimini
