Cl AlCl 3 Complexation between AlCl, a strong Lewis acid and 1-chloropropane leads to .. Cl AlCl 3 δ + δ - This species can be attcked in the usual way be the pi elelcrons of the benzen ring to give propyl benzene. The polarized intermediate is almost a primary cation, it can rearrange to forma a more stable isopropyl cation which then reacts with benzene to give the isopropyl benzene H H 3 C H 3 C H (+) AlCl 4 (-) 3. Complexation between the AlCl 3 and the FeCl 3 or AlCl 3 leads to an incipient primary carbocation that rearranges to a secondary one. Same as above CH 3 H (+) CH 3 H H (+) loss of a beta H leads to re-aromatization and the product 4 a) O only the para isomer. The reagent is very bulky and thus no , or very little ortho isomer forms 5 OCH 3 OCH 3 H 3 C CO 2 H CH 3 OCH 3 Cl CO 2 H NO 2 +++ +++ and + --- and + +++ and - --- and --- fastest slowest
