Alkynylalanes provide a new, copper-free route to skipped diynes when combined with propargylic electrophiles bearing an aluminum-complexing leaving group. The reaction is mild, efficient, and, in contrast to copper-mediated methods, highly regioselective. [reaction: see text]
与带有铝络合离去基团的炔丙基亲电试剂结合使用时,炔基丙炔为跳过的二炔提供了一种新的无铜途径。该反应温和,有效,并且与铜介导的方法相反,具有高度区域选择性。[反应:看文字]
