Various allyl alcohol derivatives containing OAlR2, OPO(OR)2, and OSiR3 groups, in addition to allylic halides and acetates, participate in the Pd-catalyzed coupling reaction with alkenyl- and arylmetals, such as those containing Al, Zn and Zr.to give the corresponding cross-coupled products, the order of their reactivity being: halogen, OAc > OAlR2 > OPO(OR)2 > OSiR3.
除烯丙基卤化物和乙酸盐外,各种包含OAlR 2,OPO(OR)2和OSiR 3基团的烯丙醇衍生物也参与Pd催化的与烯基和芳基金属的偶联反应,例如含有Al,Zn和Zr的那些给出相应的交叉偶联产物,其反应顺序为:卤素,OAc> OAlR 2 > OPO(OR)2 > OSiR 3。
