A metal-free coupling reaction between 1,3-diarylpropynes and alcohols/phenols/acids via propargylic sp3 C–H bonds activation and C–O bond formation reaction promoted by DDQ was realized. The reaction afforded series of propargyl ethers, propargyl esters and propargyl ketals.
通过炔丙基sp 3的C–H键活化和DDQ促进的C–O键形成反应,实现了1,3-二芳基丙炔与醇/酚/酸之间的无金属偶联反应。反应得到一系列炔丙基醚,炔丙基酯和炔丙基缩酮。
