We have examined the reaction of ethyl bromodifluoroacetate (1) in the presence of copper powder as a procedure for the synthesis of compounds containing a CF2 group. The complex formed in the above reaction reacted with vinyl or aryl iodides to give cross-coupling products, with Michael acceptors to give 1,4-addition products and with olefins to give radical addition products. The cross-coupling reaction
我们已经研究了在铜粉存在下溴二氟乙酸乙酯(1)的反应,作为合成含有CF 2基团的化合物的方法。在上述反应中形成的配合物与乙烯基或芳基碘化物反应,得到交叉偶联产物,与迈克尔受体得到1,4-加成产物,与烯烃得到自由基加成产物。将交叉偶联反应用于4,4-二氟-α-生育酚的合成。
