で表されるシリルエノールエーテル化合物を、トリアルキルボラン及び分子状酸素の存在下、ヨウ化トリフルオロメタンと反応させ、一般式(2)
で表されるα−トリフルオロメチルケトン化合物を製造する方法において、ジアルキル亜鉛を存在させて反応させることを特徴とするα−トリフルオロメチルケトン化合物の製造方法。
以下に実施例を用いて本発明を詳細に説明するが、本発明はこの実施例によって限定されるものではない。
ジエチル亜鉛/ヘキサン溶液を用いなかったこと以外は実施例1と同様の操作を行い反応を行った。反応液をベンゾトリフルオライドを内部標準として、19F−NMRにて分析したところ、2−(トリフルオロメチル)シクロヘキサノンの収率は6%であった。
