A novel supramolecular complex [Ag(L)(NO3)] (1) was synthesized by reaction of the oxazoline-containing ligand 1,4-bis(4,5-dihydro-2-oxazolyl)benzene (L) with silver(I) nitrate and its structure was determined by single-crystal X-ray diffraction. Structurally speaking, the one-dimensional (1D) zigzag chains of 1, in which the Ag(I) is three-coordinated with distorted trigonal-planar coordination geometry, are linked together by the hydrogen bonding interactions to form a three-dimensional (3D) supramolecular structure. It was found that the silver supramolecule 1 catalyzes the three-component coupling reactions of aldehyde, alkyne, and amine in the air at room temperature to generate propargylic amines with high efficiency. No additional co-catalyst or activator is required. A variety of aldehydes and amines were used to demonstrate the versatility of the reaction.
通过含噁唑啉配体 1,4-双(4,5-二氢-2-噁唑基)苯(L)与硝酸银(I)的反应,合成了一种新型超分子配合物 [Ag(L)(NO3)](1),并通过单晶 X 射线衍射测定了其结构。从结构上看,1 的一维(1D)人字链(其中 Ag(I)为三配位,具有扭曲的三叉平面配位几何形状)通过氢键相互作用连接在一起,形成三维(3D)超分子结构。研究发现,银超分子 1 可在室温空气中高效催化醛、炔和胺的三组分偶联反应,生成丙炔胺。无需额外的助催化剂或活化剂。为了证明该反应的多功能性,我们使用了多种醛和胺。
