  Ethynylferrocene insertion into Fe–C bond in bridging aminocarbyne diiron complexes: New triiron vinyliminium complexes

  摘要：

  The m-aminocarbyne complexes [Fe-2{mu-CN(Me)(R)}(mu-CO)(CO)(NCMe)(Cp)(2)][SO3CF3] (R = Me, 1a; Xyl, 1b; Xyl = 2,6-Me2C6H3) react with ethynylferrocene to give the corresponding bridging vinyliminium complexes [Fe-2{mu-eta(1):eta(3)-C=N(Me)(R)CHC(Fc)}(mu-CO)(CO)(Cp)(2)][SO3CF3] (R = Me, 2a; R Xyl, 2b). Insertion of the ethynylferrocene in the metal-carbyne bond is regiospecific, and leads to the formation of only one isomer.Complexes 2a and 2b undergo hydride addition (by NaBH4) affording the enaminoalkylidene complex [Fe-2{mu-eta(1):eta(3)-C(H)(N(Me)(2))CHC(Fc)}(mu-CO)(CO)(Cp)(2)] (3a) and the bis-alkylidene [Fe-2{mu-eta(1):eta(2)-C(N(Me) (Xyl))CH2C(Fc)}(mu-CO)(CO)(Cp)(2)] (3b), respectively. Upon treatment with NaH, compounds 2a and 2b undergo fragmentation, affording the 1-metalla-2-aminocyclopenta-1,3-dien-5-one complexes [Fe(CO)(Cp){C(N(Me)(R))}CHC(Fc)C(O)}] (R = Me, 4a; R = Xyl, 4b).The molecular structures of 2b, 3b and 4b have been determined by X-ray diffraction studies.
