Copper oxide nanoparticles catalyzed vinylation of imidazoles with vinyl halides under ligand-free conditions
摘要:
Recyclable copper oxide nanoparticles catalyzed most efficient and straightforward protocol for the vinylation of imidazoles with vinyl halides under ligand-free conditions. Utilizing this protocol various imidazoles were cross-coupled with different substituted vinyl halides to get the corresponding products in excellent yields with the retention configuration.
