SUMMARY
For Grignard synthesis, anhydrous diethyl ether is commonly used, but tetrahydrofuran (THF), dioxane, and glyme (MeOCh2CH2OMe) are also effective solvents. A good solvent for Grignard reactions must be non-reactive with Grignard compounds and should be dried prior to use, typically by passing through a short pad of basic alumina. Water miscibility is a critical factor, as any water presence can terminate the reaction. Understanding these solvent properties is essential for successful Grignard synthesis.
