A crystalline σ complex of copper.

摘要: Over the last decades, our understanding of σ-bond activation at transition metals has progressed considerably from both fundamental and synthetic points view thanks to preparation characterization a variety σ complexes. Here we report synthesis structural analysis first complex involving coinage metal. The copper(I) 2 derived diphosphine−disilane [Ph2P(C6H4)Me2Si−SiMe2(C6H4)PPh2] (1) been isolated crystallographically characterized. coordination Si−Si bond copper was thoroughly analyzed by quantum-chemical methods.
