Control confirmed: Optimization of P,N‐bidentate ligands (L) reveals the importance of conformation control for intermolecular trapping of reactive α‐oxo gold carbene intermediates. As a result, the highly efficient and broadly applicable synthesis of carboxymethyl ketones from readily available carboxylic acids and terminal alkynes proceeds under mild reaction conditions.
控制确认:P,N-双齿配体 ( L ) 的优化揭示了构象控制对于反应性 α-氧代金卡宾中间体的分子间捕获的重要性。因此,在温和的反应条件下,可以从易得的羧酸和末端炔烃高效且广泛地合成羧甲基酮。
