1) Lithium Diisopropyl amide (LDA) 3Lalum Dinagyang niece
(3 pts) Lithium diisopropyl amide (LDA) could theoretically act as a nucleophile or a base. With that in mind, draw the four theoretical products (3 from E2 and 1 from SN2) of the reaction below. Then, circle the major product. Provide a brief rationale. 2. Br N Li
2. Starting from CH CH.Br and diisopropyl amine, describe how you would prepare lithium diisopropyl amide (LDA), LINR, where R=Isopropyl. (5 points) 3. Write the products of the reactions below. (20 points). add to LDA -78 work up with HCI work up with HCI
please help
