Synthesis of Diynes from 1-(2,2-Dibromovinyl)-2-(Phenylethynyl)Benzene and Imidazole/Benzimidazole Via a Cui/Pd(Oac)2 Catalysed Cascade Reaction
摘要:
A novel reaction between 1-(2,2-dibromovinyl)-2-(phenylethynyl)benzene and imidazole/benzimidazole catalysed by CuI and Pd(OAc)(2) gave the corresponding highly sterically hindered diynes via a cascade elimination/Ullmann-type C-N coupling process.
