(b)
Interpretation:
The given conversion is to be accomplished with the help of enamine synthesis using pyrrolidine as the secondary amine.
Concept introduction:
When aldehydes or ketones react with a secondary amine, formation of enamine takes place. The nitrogen analog of an enol is known as enamine. From the resonating structures of enamine, it is clear that it nucleophilic in nature. Reactivity of enamines is higher than an enol but less than an enolate ion. Milder conditions are favourable for enamine reactions.

- 2) (4 pt) After the reaction was completed, the student collected the following data. Crude product data is the data collected after the reaction is finished, but before the product is purified. "Pure" product data is the data collected after attempted purification using recrystallization. Student B's data: Crude product data "Pure" product data after recrystallization Crude mass: 0.93 g grey solid Crude mp: 96-106 °C Crude % yield: Pure mass: 0.39 g white solid Pure mp: 111-113 °C Pure % yield: a) Calculate the crude and pure percent yields for the student's reaction. b) Summarize what is indicated by the crude and pure melting points.arrow_forwardDon't used hand raitingarrow_forwardDon't used hand raitingarrow_forward
