Copper(I)-Catalyzed Deacetylenative Coupling of Propargylic Amines: An Efficient Synthesis of Symmetric 1,4-Diamino-2-butynes. -The deacetylenative coupling reaction of two terminal propargylic amines is accomplished in the presence of a copper(I) catalyst and the absence of a base to give the diami
