A nickel-catalyzed method for the three-component coupling of alkenes (ethylene and alpha olefins), aldehydes, and silyl triflates is described, and this process represents the first catalytic method for coupling aldehydes and alkenes to give allylic alcohol derivatives. Conceptually, the alkene functions as a replacement for an alkenylmetal reagent.
描述了一种镍催化的烯烃(乙烯和α-烯烃)、醛和三氟甲磺酸硅酯的三组分偶联方法,该过程代表了将醛和烯烃偶联以生成烯丙醇衍生物的第一种催化方法。从概念上讲,烯烃起到了烯基金属试剂替代物的作用。
