Question

Quizplus · Accepted Answer

Ether solvents act as Lewis bases and coordinate to the Mg atom in the Grignard reagent, stabilizing it and increasing its reactivity. This coordination also helps to prevent unwanted side reactions, such as the formation of magnesium oxide or hydroxide, which can occur in the presence of water or other protic solvents. THF is a commonly used ether solvent for Grignard reactions because it is readily available and promotes high yields and selectivity for a wide range of substrates. Diethyl ether is also a common solvent for Grignard reagents, but it may be less stable than THF and less effective for some reactions.
