  Synthesis and reactivity of [M(η3-allyl)(η2-amidinato)(CO)2(phosphonium ylide)] (M = Mo, W): Investigation of the ligand properties of phosphonium ylides

  摘要：

  Phosphonium ylide complexes of Mo and W formulated as [M(eta(3)-allyl){eta(2)-(NPh)(2)CH}(CO)(2)(CH2PR3)] (M = Mo, R = Me: 2a-Mo; M = Mo, R = Ph: 2b-Mo, and M = W, R = Me: 2a-W) were prepared by the reaction of amidinato(pyridine) complex, [M(eta(3)-allyl){eta(2)-(NPh)(2)CH}(CO)(2)(NC5H5)] (M = Mo: 1-Mo and M = W: 1-W), with a phosphonium ylide, CH2PR3 (R = Me, Ph), which was generated in situ by the reaction of the corresponding phosphonium salt with (BuLi)-Bu-n. These complexes were characterized spectroscopically, as well as by the X-ray diffraction. The phosphonium ylide ligand shows stronger electron donating ability toward the metal than N-heterocyclic carbene or phosphine ligands. This trend is supported by the comparison of the spectroscopic data and the DFT calculations. We also investigated the reactivity of the phosphonium ylide complexes 2-Mo with two-electron donors such as PEt3 and NHC. In the case of the PPh3 ylide complex (2b-Mo), the substitution reaction of the ylide ligand for the two-electron donors took place cleanly to yield the corresponding complexes. On the other hand, in the PMe3 ylide complex (2a-Mo), the substituted complexes formed but the unreacted ylide complex 2a-Mo was also present in the reaction mixture. These results show that the bond strength of the M-C(phosphonium ylide) bond is affected by the substituents on the phosphorus atom. (C) 2017 Elsevier B.V. All rights reserved.

  The molybdenum complex [Mo(η 3 -allyl)Cl(CO) 2 (NCMe) 2 ] (1) reacted with two equivalents of amidines, ArN=C(R)NHAr (R = H. CH 3 ; Ar = C 6 H 5 , p-CH 3 -C 6 H 4 ) (2), to give corresponding his(amidine) complexes, [Mo(η 3 -allyl)Cl(CO) 2 (amidine) 2 ] (3).
