A series of strong Lewis acid‐free alkoxide/siloxide‐based Mg electrolytes were deliberately developed with remarkable oxidative stability up to 3.5 V (vs. Mg/Mg 2+ ). Despite the perception of ROMgCl (R=alkyl, silyl) as a strong base, ROMgCl acts like Lewis acid, whereas the role of MgCl 2 in was unambiguously demonstrated as a Lewis base through the identification of the key intermediate using single crystal X‐ray crystallography. This Lewis‐acid‐free strategy should provide a prototype system for further investigation of Mg‐ion batteries.
