1. Oxazolines (five membered ring with N and O shown below) are an important functional group in organic chemistry because they can be used to help facilitate catalytic, enantioselective reactions during the synthesis of important pharmaceutical molecules. One way to make oxazolines is through the ring expansion of N-acylaziridines. Me Ph Nal Acetone Ph An N-Acylaziridine An oxazoline a. This reaction utilizes nucleophilic substitution reactions to get from the aziridine to the oxazoline. Provide a complete arrow pushing mechanism for this transformation. You do not have to draw it while talking. You can have the mechanism already drawn out and simply talk through the steps. If you choose to use ChemDraw, be sure it is very clear where your arrows are pointing. You may also draw it by hand (paper or tablet) and screenshare an image of your work while explaining what happens. You must talk through each step of your mechanism and use proper terms such as nucleophile and electrophile. b.…
In the presence of excess base and excess halogen, a methyl ketone is converted to a carboxylate ion. The reaction is known as the haloform reaction because one of the products is haloform (chloroform, bromoform, or iodoform). Before spectroscopy became a routine analytical tool, the haloform reaction served as a test for methyl ketones: the formation of iodoform, a bright yellow compound, signaled that a methyl ketone was present. Why do only methyl ketones form a haloform?

Br2, H3O+ གོ་ཤི་ན་ཤི་ H3C CH3 CH3 CH3 Aldehydes and ketones can be halogenated at their a-position by reaction with Cl₂, Br2, or 12, under acidic conditions. Using Br2 under acidic conditions, an intermediate enol is formed which adds bromine at the a-position. The reaction stops after the addition of one bromine because the electron-withdrawing halogen decreases the basicity of the carbonyl oxygen, making the protonation less favorable. Draw curved arrows to show the movement of electrons in this step of the mechanism. Arrow-pushing Instructions :OH :OH Br-Br H3C H3C. Br Br CH₂ H₂ H3C CH3 H3C CH3 2b
