  Neighbouring metal induced oxidative addition at the iron centre amongst the iron–arylpyridylphosphine complexes

  摘要：

  Complexes of the type (eta(4)-BuC(5)H(5))Fe(CO)(2)(P) (P = PPh(2)Py 3, PPhPy(2) 4, PPy(3) 5; Py = 2-pyridyl) were satisfactorily prepared. Upon treatment of 3 with M(CO)(3)(EtCN)(3) (M = Mo, 6a; W, 6b), the pyridyl N-atom could be coordinated to the metal M, which then eliminates a CO ligand from the Fe-centre and induced an oxidative addition of the endo-C-H of (eta(4)-BuC(5)H(5)). This results in a bridged hydrido heterodimetallic complex [(eta(5)-BuC(5)H(4))Fe(CO)(mu-P,N-PPh(2)Py)(mu-H)M(CO)(4)] (M = Mo, 7a, 81%; W, 7b, 76%). The reaction of 4 or 5 with 6a,b did not give the induced oxidative addition, although these complexes contain more than one pyridyl N-atom. The reaction of 4 with M(CO)(4)(EtCN)(2) (M = Mo, 9a; W, 9b) produced heterodimetallic complexes [(eta(4)-BuC(5)H(5))Fe(CO)(2)(mu-P:N,N'- PPhPy(2))M(CO)(4)] (M = Mo, 10a, 81%; W, 10b, 83%). Treatment of 5 with 6a, b gave [(eta(4)-BuC(5)H(5)) Fe(CO)(2)(mu-P:N,N',N ''-PPy(3))M(CO)(3)] (M = Mo, 12a, 96%; W, 12b, 78%). (C) 2008 Elsevier B.V. All rights reserved.

  Dropwise addition of an excess amount of HBF4. OEt2 through a pressure equalizing funnel to (eta (4)-BuC5H5) Fe(CO)(2)PPh3-nPyn resulted in [(eta (5) -BuC5H4)Fe(CO)(2)PPh3-n Py-n(+)][BF4-]. The smooth abstraction of the endo-H atom of (eta (4)-BuC5H5)Fe(CO)(2)PPh3-nPyn is a result of the hydridic nature of this hydrogen. HBF4. OEt2 which worked better than an other Lewis acid, Ph3C+PF6-, because the H-2 produced in the course of the reaction could be removed, whereas Ph3CH remains in the solution along with a catonic species which is partially soluble in THF. The hydride abstraction of the neutral complexes was followed spectroscopically.
