9.3: Reactions of Alkynes - Addition of HX and X₂
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 ). WebJan 23, 2024 · Benzene reacts with chlorine or bromine in an electrophilic substitution reaction, but only in the presence of a catalyst. The catalyst is either aluminum chloride (or aluminum bromide if you are reacting benzene with bromine) or iron. Strictly speaking iron is not a catalyst, because it gets permanently changed during the reaction. cajamarca maps
