摘要
The α-zincated derivatives of N,N-dimethylacetamide and trimethylphosphine oxide by H-Zn exchange with the organozinc precursor LZn 2Ph 2 were structurally characterized. The solid-state structure of LZn 2[CH 2P-(O)Me 2] 2 was determined by X-ray diffraction. The diasterotopic methylene (Zn-Ch 2-) was observed as a pair of upfield resonances at σ 0.80 and 0.03 ppm. The structural characterization of α-zincated derivatives show that the deprotonated amide and phosphine oxide molecules function as 1,3-bridging ligands between two Zn centers, both in solution and in the solid state.
