Gold(III) complexes of a series of polydentate pyridine‐ and quinoline‐based ligands are prepared. The coordination ability of the pyridine and quinoline nitrogen atoms are different. All complexes are catalytically active in cyclopropanation of propargyl ester and styrene and outperform KAuCl₄. Pyridine‐N decoordination may be a crucial step for generation of catalytic activity.

吡啶和喹啉基金（III）配合物：合成，表征和应用

制备了一系列多齿吡啶和喹啉基配体的金（III）配合物。吡啶和喹啉氮原子的配位能力不同。所有的配合物在炔丙基酯和苯乙烯的环丙烷化中均具有催化活性，其性能优于KAuCl ₄。吡啶-N去配位可能是产生催化活性的关键步骤。
