The first report of 1,2-dicarbofunctionalization of alkynes using organohalides as coupling partners in the field of gold catalysis has been presented. Mechanistic investigations, including NMR, tandem mass spectrometry and DFT studies, reveal that an oxidative addition/carbophilic activation pathway is preferred over the migratory insertion/cis-trans isomerization pathway.
首次报道了金催化领域中使用有机卤化物作为偶联伙伴的炔烃 1,2-二碳官能化反应。包括 NMR、串联质谱和 DFT 研究在内的机理研究表明,氧化加成/亲碳活化途径优于迁移插入/顺反异构化途径。
