The cross-coupling reaction of allylic carbonates with organosilanes was found to proceed without fluoride ion activation under mild conditions by using a coordinatively unsaturated palladium complex as a catalyst. The reaction was assumed to proceed through an allylpalladium alkoxide derived from the allylic carbonate substrate and a palladium(0) species, the alkoxo ligand activating the organosilicon
通过使用配位不饱和钯配合物作为催化剂,发现烯丙基碳酸酯与有机硅烷的交叉偶联反应在温和条件下无需氟离子活化即可进行。假设该反应通过衍生自烯丙基碳酸酯底物的烯丙基钯醇盐和钯 (0) 物质进行,烷氧基配体激活有机硅试剂。同样,一氧化二烯也以中等至高产率与烯基和芳基氟硅烷进行交叉偶联。
