| Abstract: | A 'Ga'llant couple: The α-alkenylation of esters was accomplished by GaBr(3) -catalyzed coupling between alkenyl ethers and ketene silyl acetals. In this reaction system, various alkenyl ethers, including those with vinyl and substituted alkenyl groups, were applicable, and the scope of applicable ketene silyl acetals was sufficiently broad. The mechanism is also discussed. |
