The addition of a Lewis acidic metal triflate salt Mg(OTf)2 as co-catalyst in the CpRu-catalyzed decarboxylative allylation of in situ-generated ketone enolates allows the reaction to proceed at lower temperature with higher regio- and enantioselectivity. Even so-far-unreactive substrates react.
在原位产生的酮烯醇酸酯的CpRu催化的脱羧烯丙基化中加入路易斯酸酸性三氟甲磺酸盐Mg(OTf)2作为助催化剂可以使反应在较低的温度下以较高的区域和对映选择性进行。甚至到目前为止没有反应的底物也会发生反应。
