The intermolecular α-arylation and vinylation of amides by palladium-catalyzedcoupling of aryl bromides and vinyl bromides with zinc enolates of amides is reported. Reactions of three different types of zinc enolates have been developed. The reactions of aryl halides occur in high yields with isolated Reformatsky reagents generated from α-bromo amides, with Reformatsky reagents generated in situ from
报道了通过芳基溴化物和乙烯基溴化物与酰胺的烯醇锌的钯催化偶联,酰胺的分子间α-芳基化和乙烯基化。已经开发了三种不同类型的烯醇化锌的反应。芳基卤化物与由 α-溴酰胺产生的分离的 Reformatsky 试剂、由 α-溴酰胺原位产生的 Reformatsky 试剂以及通过用氯化锌淬灭酰胺的烯醇锂而产生的烯醇锌以高产率发生反应。这种使用锌烯醇化物代替碱金属烯醇化物极大地扩展了酰胺芳基化的范围。该反应在室温或 70 °C 下与含有氰基、硝基、酯、酮、氟、羟基或氨基官能团的溴芳烃以及溴吡啶发生反应。此外,该反应已开发与吗啉酰胺,其产物是酮和醛的前体。酰胺的烯醇锌的芳基化是用带有受阻五苯的催化剂进行的...

The Ketene-Surrogate Coupling: Catalytic Conversion of Aryl Iodides into Aryl Ketenes through Ynol Ethers
作者:Wenhan Zhang、Joseph M. Ready
DOI:10.1002/anie.201405036
日期:2014.8.18
tert‐Butoxyacetylene is shown to undergo Sonogashira coupling with aryliodides to yield aryl‐substituted tert‐butyl ynol ethers. These intermediates participate in a [1,5]‐hydride shift, which results in the extrusion of isobutylene and the generation of aryl ketenes. The ketenes are trapped in situ with multiple nucleophiles or undergo electrocyclic ring closure to yield hydroxynaphthalenes and quinolines
