couple: The α‐alkenylation of esters was accomplished by GaBr3‐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.
A“Ga'llant夫妇:酯的α烯基化物通过贾布尔完成3链烯基醚和甲硅烷基烯酮缩醛之间催化的耦合。在该反应体系中,各种链烯基醚,包括那些具有乙烯基和取代的链烯基,被适用,并适用烯酮甲硅烷基乙缩醛的范围为足够宽。的机理进行了讨论。
