In Parts 2 and 3, draw the reagents necessary to prepare this product through two different reactions. Сн, H.C

Answer 1

Organocuprates are used to react with ketones and aldehydes that are $\alpha \beta$ unsaturated. Due to the phenyl ring, this compound satisfies the condition and hence is preferred over lithium compounds.
