β-Bromovinyl ethyl ether smoothly couples with Grignard reagents in the presence of [Ni(dppp)Cl2] as a catalyst to give the corresponding alkylated and arylated vinyl ethers in good yields. This reaction provides a new one-step, functionalized two-carbon homologation of Grignard reagents.
在[Ni(dppp)Cl2]作为催化剂的存在下,β-溴乙烯基乙醚与格氏试剂顺利偶联,以良好的收率得到相应的烷基化和芳基化乙烯基醚。该反应为格氏试剂提供了一种新的一步功能化的双碳同源性。
