Copper nanoparticle-catalyzed cross-coupling of alkyl halides with Grignard reagents
作者:Ju Hyun Kim、Young Keun Chung
DOI:10.1039/c3cc46419a
日期:——
A cross-coupling reaction between alkyl bromides and chlorides and various Grignardreagents was carried out in the presence of commercially available copper or copper oxide nanoparticles as a catalyst and an alkyne additive. The catalytic system shows high activity, a broad scope, and good functional group tolerance.
