Synthesis and Structural Characterization of Arsinoamide and its Metal Complexes

The phosphinoamide chemistry has attracted a considerable attention owing to the structural diversity of the associated complexes.[16-21] To further understand the properties of the P-N bond, Ashby synthesized the compound [(Ph2P-NPh)Li(Et2O)]2 (Figure 1.1.1) through the deprotonation reaction of the corresponding aminophosphine with nBuLi.[22] X-ray diffraction analyses indicated the presence of Li-P bonds (2.684(3) and 3.004(4) Å). In addition, the P-N bond length (1.672(2) Å) was relatively smaller than that of a single bond (mean value of 1.70
