Unsaturated vicinal frustrated phosphane/borane Lewis pairs as ligands in gold(i) chemistry (Ueno, Atsushi; Watanabe, Kohei; Daniliuc, Constantin G.; Kehr, Gerald; Erker, Gerhard)
Chem. Commun. 2019, 55 (30), 4367−4370.

Keywords: frustrated Lewis pair; B; P; Au; Mes; dimethyl sulfide; hydroamination

エチレン系ホウ素/リンフラストレイテットルイスペアを配位子とする金錯体の構造と機能について報告しているようです。

ルイスペア分子と塩化金(I)ジメチルスルフィド錯体を反応させるとリン原子が金に配位した5員環に近い構造の錯体が生成。塩化金由来の塩化物イオンを交換反応によりスルホニルイミドとすることができ、そのスルホニルイミド錯体がアルキンのヒドロアミノ化の触媒となる、というストーリーだと想像できます。

Mesはメシチル基。

ところで、これらの錯体の5員環構造、本当に著者らが期待したものなのでしょうか。本当はルイスペアと金、金化合物由来のアニオンからなる6員環の構造を狙って検討を行ったのではないか、と勝手に想像しています。ホウ素原子に配位しやすいフッ化物とかそういうのも検討したんじゃないかなとか、ね。

というわけで、論文のストーリー全体に興味がありますので、読みたい論文に追加です。

ジメチルスルフィドはどこへいってしまったのでしょうね。
