Several alkenyltrialkylborate salts derived from the reaction of α-methoxyvinyllithium (MVL) with trialkylboranes have been prepared. At −80°C, the initial complex is stable as indicated by its iodination to give moderate yields of enol ethers. Warming the complex to room temperature leads via an alkyl group migration to a new alkenyldialkylmethoxyborate salt. Oxidation of this complex leads to methyl
