The mechanism for the reaction between Grignard reagent and oxetane to produce primary alcohol is to be proposed and the reason corresponding to the fact that oxetane reacts with Grignard reagent even though most ethers do not is to be stated. Concept introduction: The reaction of metals like lithium and magnesium with vinyl halides, alkyl halides and aryl halides gives organometallic compound as a product. The compounds in which carbonyl groups are present like ketone or aldehyde react with Grignard reagent to form alcohol. The examples of Grignard reagent are ethyl magnesium bromide and PhMgBr . Ether is used as the solvent in the Grignard reactions. To determine: The mechanism for the reaction between Grignard reagent and oxetane to produce primary alcohol and the reason corresponding to the fact that oxetane reacts with Grignard reagent even though most ethers do not.
