我们报道了三种新的 Cu(I) σ-配合物的合成和分离，其中 E-H (E = Al, Zn) σ-键与铜配位。将主族氢化物添加到甲苯溶剂化的 Cu(I) 配合物中会导致可逆的配体交换，并且 Cu(I) σ 配合物已结晶。实验和计算数据提供了大量证据，证明E-H键与Cu(I)的弱结合，这可归因于E-H键向铜的4s轨道的σ供体以及铜向E-H σ*轨道的反供体。
We report the synthesis and isolation of three new σ-complexes of Cu(I) in which E–H (E = Al, Zn) σ-bonds are coordinated to copper. The addition of the main group hydride to a toluene-solvated Cu(I) complex results in reversible ligand exchange, and the Cu(I) σ-complexes have been crystallized. Experimental and computational data provide a wealth of evidence for weak binding of the E–H bond to Cu(I), which can be ascribed to σ-donation from the E–H bond into the 4s orbital of copper and back-donation from copper into the E–H σ* orbital.
