Metal acetylide elimination facilitates a novel one-pot cascade metalation and elimination/addition route to a series of unsymmetrical secondary amines from the reaction of secondary propargylamines with organometallic reagents. Spectroscopic evidence suggests a dimetalated amido intermediate rather than an allene.
金属乙炔化物的消除促进了新颖的一锅级联金属化以及从仲炔丙胺与有机金属试剂的反应中向一系列不对称仲胺的消除/加成途径。光谱证据表明是双金属酰胺中间体而不是丙二烯。
