  Attempted Synthesis of 1-Aza-3λ³-phospha-1-allenide Complexes:  Structure and Reactions of an Unusual Phosphanide Complex

  摘要：

  Synthesis of the first N-lithiated cyanophosphanide complexes 5a-c was achieved via reaction of complex 1 with (BuLi)-Bu-t/12-crown-4, NaN(SiMe3)(2)/15-crown-5, or (KOBu)-Bu-t/18-crown-6 at low temperature. Compounds 5a-c were isolated and fully characterized by NMR and IR spectroscopy and elemental analysis. The structure of complex 5a, as established by X-ray diffraction studies, revealed that the lithium is coordinated to nitrogen and the oxygen centers (of the crown ether unit). This geometry of 5a is best described as a phosphanide complex isomeric to a phosphinidenoid complex. A phosphinidenoid-like behavior of 5a was observed in the melt, evidenced by formation of cyclotriphosphane 4 via LiCN elimination and decomplexation. In solution 5a reacted with methyl iodide (or methyl triflate) like a phosphanide, thus leading to P-methyl complex 8.
