WebCollege of Arts and Science Vanderbilt University WebAcetophenone is a methyl ketone. The addition of Br and NaOH sets up the conditions for the haloform reaction. This reaction turns a methyl ketone into haloform and an acid (or its conjugate base). In this case, the following reaction would occur: I’ve taken some liberties with this reaction.

WebCatalytic Hydration of Alkenes. In this reaction you end up adding water to your alkene. Since water is not nearly acidic enough to protonate the double bond of an alkene by itself, you’ll need a strong acid as a catalyst. You would typically see something like sulfuric acid (H 2 SO 4) as a catalyst in this reaction. WebFor this reaction Cl 2, Br 2 or I 2 can be used as the halogens. General reaction Example 22.3.1 Acid Catalyzed Mechanism Under acidic conditions the reaction occurs thought … WebIn a one-pot cascade transformation of ketones into α-imidoketones, N-bromosuccinimide (NBS) provides both electrophilic bromine and nucleophilic nitrogen sources, and diazabicyclo[5.4.1]undec-7-ene (DBU) functions as a base and a nucleophilic promoter for the activation of NBS. α-Bromination is supposed as the key step in the process. irem project directory
