WebThe Williamson ether synthesis is an SN 2 reaction in which an alkoxide ion is a nucleophile that displaces a halide ion from an alkyl halide to give an ether. The reaction occurs with inversion of configuration at chiral centers and can be limited by possible competing elimination reactions. Intramolecular Williamson ether synthesis occurs at ... WebThis then couples with the alkyl radical formed. q Diethyl ether is an especially good solvent for the formation of Grignard reagents because ethers are non-acidic (aprotic). Water or alcohols would protonate and thus destroy the Grignard reagent, because the Grignard carbon is highly nucleophilic. This would form a hydrocarbon.
