WebJul 31, 2024 · Halogenation of saturated aldehydes and ketones usually occurs exclusively by replacement of hydrogens alpha to the carbonyl group: The reagents that commonly are used to halogenate carbonyl compounds are those that are used to halogenate alkanes (e.g. \ce {Cl_2}, \ce {Br_2}, \ce {SO_2Cl_2}, and N -bromoamides; see Sections 4-4 and 14-3 ). AlCl3 is a powerful Lewis acid. It reacts vigorously and irreversibly with Lewis bases. With water it forms the hexaaquoaluminum (III) ion, Al (H2O)_6^3+. This means that it can no longer behave as a Lewis acid and is therefore unable to catalyze the Friedel-Crafts reaction. ( 5 votes) umang.mathur.85 12 years ago
