This study reports the synthesis of diverse β-functionalized ketones from readily available 1-arylallylic alcohols in the presence of (trimethylsilyl)methylpotassium (TMSCH₂K). The reaction proceeded via the formation of the highly nucleophilic dipotassio α,β-dianion as the key intermediate, which served as a metal homoenolate equivalent. This protocol also allowed the one-pot synthesis of α,β-difunctionalized ketones using two different electrophiles, thus demonstrating its synthetic advantages over other protocols involving metal homoenolates.

1-芳基烯丙醇通过二钾 α,β-双阴离子中间体制备 β-官能化和 α,β-双官能化酮

_{本研究报道了在（三甲基甲硅烷基）甲基钾 (TMSCH 2} K)存在的情况下，从现成的 1-芳基烯丙醇合成多种 β-官能化酮。反应通过形成高度亲核的双钾 α,β-二价阴离子作为关键中间体，作为金属均烯醇化物等价物进行。该协议还允许使用两种不同的亲电子试剂一锅法合成 α,β-双官能化酮，从而证明其相对于其他涉及金属均烯醇化物的协议的合成优势。
