  Phosphorus Ylide as a Precursor for the Formation of New High-Valent Tantalum Phosphonio Methylidyne Complexes

  摘要：

  Two new high-valent tantalum(V) phosphonio methylidyne complexes, [CpTa(C-PPh3)(CH-PPh3)Cl] (4) and [CpTa(C-PPh3)(CH-PPh3)(2)] (5), have been obtained respectively via transylidation reactions of CpTaCl4 with 5 and 7 equiv of the phosphorus ylide Ph3PCH2. Complex 4 was structurally analyzed with X-ray diffraction. The possible formation mechanism has been discussed. To our knowledge this presentation is the first example of a stable tantalum complex with a terminal [MC-PPh3] function.
