The coupling reaction of iodobenzene with allylic diols in the presence of Pd(OAc)2 and nBu3P as catalysts using K2CO3 as base afforded the phenyl-substituted allylic diols. However, under the same reaction conditions with Et3N as base, phenyl-substituted α-hydroxy ketone was obtained.
以K 2 CO 3为碱,在Pd(OAc)2和n Bu 3 P作为催化剂的存在下,
碘苯与烯丙基二醇的偶联反应得到了苯基取代的烯丙基二醇。然而,在以Et 3 N为碱的相同反应条件下,获得了苯基取代的α-羟基酮。
