The First Mixed-Anion Complex of a Lithium Phosphazene: Synthesis and Crystal and Solution Structure of [(LiCH2P(Ph)2=NPh)·(LiOC6H2-2,6-{C(CH3
文摘
The crystal and toluene solution structure (X-ray, 1H, 7Li, 13C,31P NMR) of a mixed-anionlithium phosphazene-phenolate, 10, is a six-rung ladder consisting of two LiPCN units fusedto a central Li2O2 core, which provides insight into the function of phosphazenyl-stabilizedcarbanions as reagents. The mixed aggregate showed decreased reactivity toward benzaldehyde with respect to the uncomplexed anion.
