benzofuran core through a cascade of copper‐catalyzed processes wherein the key carbon atom comes from the dimethylacetamide (DMA) solvent. Strong evidence for the participation of a Wacker cyclization catalyzed solely by copper is provided, not only in the title reaction from benzophenones but also from 2‐hydroxy‐α‐arylstyrene derivatives.
DMA捐赠:乙酸铜(II)和8-羟基喹啉通过一系列铜催化过程来促进苯并呋喃核的形成,其中关键碳原子来自二甲基乙酰胺(DMA)溶剂。有力的证据证明了仅由铜催化的瓦克环化反应不仅在二苯甲酮的标题反应中,而且在2-羟基-α-芳基苯乙烯衍生物的反应中也有提供。
